Detection of Electric Vehicle Charging Events Using Non-Intrusive Load Monitoring

Rohit Kerekoppa Ramesha,SS 2022, Projekt Homepage

Non-intrusive load monitoring (NILM) is the process of using the energy consumption of a house as a time series, which is the sum of the consumptions of the individual appliances to predict the individual appliance’s consumption time series. NILMTK[1] is an open-source toolkit for comparative analysis of NILM algorithms across various datasets. The goal of this project is to use NILMTK to predict the energy consumed while charging electric vehicles from overall energy consumption of a house using a synthetic dataset.

 

Question Answering on Wikidata

David Otte,SS 2022, Projekt Homepage

Aqqu is an efficient question answering system that was developed using Freebase. This project aims to implement Aqqu for question answering on Wikidata instead of Freebase and to improve the accuracy of previous implementations using Wikidata. In short, for a given natural language question, SPARQL queries that might answer the question are generated and ranked afterwards in order to get the query that is most likely to answer the given question.

 

Testing and improving Antpower on the Simbench networks

Metty Kapgen,SS 2022, Projekt Homepage

The project aims to test and improve Lukas Gebhard’s Antpower on the Simbench Networks provided by Fraunhofer ISE. In short Lukas has developed a solver that is able to produce a cheap expansion plan given a low voltage grid. In this project we aim to test his solver on a small and synthetic set of low-voltage grids called the Simbench networks. At its core, Antpower uses the ant colony optimization algorithm to produce cheap expansion plans. Those are needed as the current state of the grid can contain several overloaded components which need to be upgraded with better but more expensive cable types. This project will show that, given a large computation time, Lukas’ Antpower produces good solutions.

 

Wikipedia Entity Linking and Coreference Resolution in C++

Benjamin Dietrich,SS 2022, Projekt Homepage

Implementing a C++ version of an already existing Python based entity linking and coreference resolution system for Wikipedia was what this project was aiming for. The goal was to improve the runtime of the system while maintaining the already good linking results. How this goal was achieved will be discussed in this article.

 

Project Map Matching Mobile Phones to Public Transit Vehicles

Gerrit Freiwald, Robin Wu,SS 2022, Projekt Homepage

Map matching can be used to match a given sequence of GPS points to a digital model of the real world. ‘Traditional’ map matching, like navigation systems for cars, uses a static map for the matching. In contrast, when working with a public transit vehicle network, the ‘map’ contains the positions of each vehicle, which are highly dynamic.

 

Projekt Public Transit Map Matching With GraphHopper

Michael Fleig, WS 2021, Projekt Homepage

TransitRouter is a web tool for generating shapes of GTFS (General Transit Feed Specification) feeds for bus routes using the map matching approach described in the paper Hidden Markov Map Matching Through Noise and Sparseness.

TransitRouter uses the OSM routing engine GraphHopper and a modified version the GraphHopper Map Matching library that enables turn restrictions and tries to prevent inter hop turns.

GraphHopper is a fast and memory efficient routing engine written in Java. It has built in support for different weighting strategies (e.g. fastest and shortest path routing), turn restrictions (based on OSM meta data), turn costs and most important the ability to specify custom routing profiles. As public transit has quite different traffic rules we created a specialized bus profile.

The quality of the results are compared with the original GraphHopper Map Matching library (GHMM) and pfaedle a similar tool developed by the chair of Algorithms and Data Structures at the University of Freiburg.

The source code of TransitRouter is available on GitHub.

 

Enhancing find functionality of pdf.js

Robin Textor-Falconi, WS 2021, Projekt Homepage

An adventure into pdf.js’ text extraction, and the ways it can be improved for better find functionality.

 

Segmentation of layout-based documents

Elias Kempf, WS 2021, Projekt Homepage

PDF is a widely used file format and in most cases very convenient to use for representing text. However, PDF is layout-based, i.e., text is only saved character by character and not even necessarily in the right order. This makes tasks like keyword search or text extraction pretty difficult. The goal of this project is to detect individual words, text blocks, and the reading order of a PDF document to allow for reconstruction of plain text.

 

Energy Price Forecasting

Sneha Senthil, WS 2021, Projekt Homepage

The project aims to predict energy prices for the next 24 hours, given the history of past features such as load, generation, prices and weather data. This data is downloaded from 2 data sources: ENTSOE and Copernicus. MLP’s, residual networks and LSTMs are trained with different hyperparameters, different subsets of features and different histories and the results are compared. The residual MLP has the best results. This is likely to due to the fact that the residual MLP can adapt to changing prices better than the other models.

 

jSPINE - A Java Library implementing EEBUS SPINE

Martin Eberle, WS 2021, Projekt Homepage

In a world with rising energy demands, power limitations by grid infrastructures and fluctuating energy supply of renewable energy sources, the communication between devices which consume electrical power is a key in distributing electricity efficiently. The EEBus Initiative e.V. provides a free and open, standardized language aiming to solve the barriers in communication between devices of different manufacturers.

 

Spelling Correction and Autocompletion for Mobile Devices

Ziang Lu, SS 2021, Projekt Homepage

A virtual keyboard is a powerful tool for smartphones, with which users can improve the quality and efficiency of the input. In this project, we will explore how to use n-gram models to develop an Android keyboard which gives accurate corrections and completions efficiently.

 

Named Entity Disambiguation with BERT

Amund Faller Råheim, SS2021, Projekt Homepage

Large transformer networks such as BERT have led to recent advancements in the NLP field. The contextualized token embeddings that BERT produces should serve as good input to entity disambiguation, which benefits from context. This master project aims to use BERT on the task of Named Entity Disambiguation.

 

Sentence Segmentation

Krisztina Agoston, SS2021, Projekt Homepage

Sentence segmentation is a basic part of many natural language processing (NLP) tasks. The leading NLP Python libraries spaCy and NLTK offer pre-trained models for that. These models often fail on a specific domain. The goal of this project is to measure the performance of these libraries and compare their results with a custom made LSTM model on special domains like Wikipedia or arXiv.

 

Automated Generation of Rail Noise Maps

Urs Spiegelhalter, SS2021, Projekt Homepage

Given a geographical network of railroads and OpenStreetMap data, automatically generate rail noise maps from this data. The results can be shown in a web application where hourly time spans, which represent typical rail schedules, can be compared.

 

Simplke Question Answering on Wikidata

Thomas Goette, WS2020/21, Projekt Homepage

Aqqu translates a given question into a SPARQL query and executes it on a knowledge base to get the answer to the question. While the original Aqqu uses Freebase and some additional external sources, this new version uses nothing but Wikidata.

 

Tokenization repair using Transformers

Sebastian Walter, WS2020/21, Projekt Homepage

This project tackles the tokenization repair problem using the Transformer neural network architecture. We achieve results that match the performance of previous work on multiple tokenization repair benchmarks paired with usable runtimes in practice.

 

Gantry

Axel Lehmann, SS2020, Projekt Homepage

Gantry allows docker-compose-like deployments with wharfer. wharfer is a replacement for the docker executable used and maintained by the Chair of Algorithms and Data Structures. Additionally, gantry allows executing containers in a sequential order. Within this sequential order, gantry tries to execute as many containers in parallel as possible. This minimizes overall execution time but keeps results deterministic.

By anticipating market movements ahead of time it is possible to generate profits. This application implements several trading strategies which aim to do that automatically.

 

 

Circular Transit Maps

Jonathan Hauser, SS 2019, Projekt Homepage

Transit Maps can be found in many places. By replacing the actual road geometry with a simpler geometry like arcs the result not only becomes more aesthetically pleasing but also more readable. Nonetheless, the original road layout shouldn’t be left completely unconsidered to avoid confusion when reading the map.

Tokenization Repair Using Character-based Neural Language Models

Matthias Hertel, WS 2018/19, Projekt Homepage

Common errors in written text are split words (“algo rithm”) and run-on-words (“runsin”). I use Character-based Neural Language Models to fix such errors in order to enable further processing of misspelled texts.

 

 

WikiQuestions

Natalie Prange, WS 2018, Projekt Homepage

Systems based on machine learning such as Question Answering or Question Completion systems require large question datasets for training. However, large question datasets that are not restricted to a specific kind of question are hard to find. The WebQuestions (Berant et al., 2013) and Free917 (Cai & Yates, 2013) datasets both contain less than 10,000 questions. The SimpleQuestions dataset (Bordes et al., 2015) contains 108,442 questions, but the questions are limited to simple questions over Freebase triples of the form (subject, relationship, object). The 30M Factoid Question-Answer corpus (Serban et al., 2016) contains 30 million questions, however, these questions, too, are limited to simple Freebase triple questions.

We introduce a question dataset containing 4,390,597 questions and corresponding answer entities that are generated by rephrasing Wikipedia sentences as questions. The rough pipeline of the question generation (QG) system is as follows: A Wikipedia dump with Freebase entity mentions is preprocessed by annotating entities with their types. The preprocessed Wikipedia dump is then parsed using a dependency parser. For each sentence, entities that fulfill certain grammatical criteria are selected as answer entities. A fitting WH-word is selected for an answer entity and various transformations are performed over the sentence to rephrase it as a question. Finally, the generated questions are filtered to avoid ungrammatical or otherwise unreasonable questions. The following section describes the system pipeline in more detail.

Concept Neurons

Joao Carvalho, WS 2018, Projekt Homepage

This webpage showcases the master project developed by João Carvalho at the Chair of Algorithms and Data Structures of the University of Freiburg, as part of the MSc degree in Computer Science.

In this project we explored the capabilities of neural language models. More precisely, we questioned if a neural network would be able to encode Part-of-Speech (POS) tags in its neurons, just by training a simple language model.

We first trained a byte-level language model with a Long Short-Term Memory (LSTM) network using a large collection of text. Then, taking a sentence, which can be viewed as a byte sequence, we used its inner representations (the cell states of the LSTM), along with its corresponding POS tags, as the inputs and targets to train a logistic regression classifier. Looking at the classifier weights, we observed that some concepts (POS tags) are encoded in one neuron, i.e., the POS tag of a byte can be derived from one neuron's activation value, while others are derived with more than one neuron together with the logistic regression classifier. For some tags, using three neurons yielded satisfactory results.

The idea for this project started from the openAI paper (Radford et al, 2017). In this article, the authors found a dimension in the cell states (a neuron) that strongly correlates to the semantic concept of sentiment, which they called the Sentiment Neuron. In this project we also replicated their results.

 

Football Data Extraction for Broccoli

Jonas Bischofberger, WS 2018, Projekt Homepage

The Broccoli search engine answers queries about a broad range of entities, but lacks information in more specific domains. The task was to choose an appropriate one of these domains, obtain relational and full-text data from that domain and integrate it into the current Broccoli version. For this project, data about association football players (e.g. height, birth date, current team) and teams (e.g. date of foundation) was chosen.

 

Search Engine for OSM Data

Iradj Solouk, WS 2018, Projekt Homepage

The actual motivation behind this project is to build an OSM-Data search engine that has comparable results as Nominatim. The aim of this project is setting up a basic web application(Parser, index structures, basic ranking and the UI) so that the application can be improved in a future work, in which one will mainly focus on the ranking functionality. In the following, the structure of the application, certain parts of it and their development will be presented. The order of presentation also reflects the order of development of the application and the logical execution sequence.

 

Tabular Information Extraction

Tobias Matysiak, SS 2018, Projekt Homepage

This project aims at simplifying the creation of SPARQL-queries for the knowledge base Freebase. Instead of finding out the relevant Freebase types and relations by hand, the user specifies table columns in a simple table description format.

 

ShapeExtraction

Mohamed Abou-Hussein, Omar Shehata, WS 2017/18, Projekt Homepage

The General Transit Feed Specification (GTFS) is a group of files that defines a common format for public transportation schedules and other geographic information. GTFS allows public agencies to publish their data to be used in the feed. The goal of the project was to build a tool (GTFS mapper) that given a GTFS feed would generate an alternative feed with the same formate and describing the same region, but using open source data. This is due to the fact that the data uploaded from the public agencies is not always sufficient.

Open Street Map (OSM) is an open source project that shows the maps of the world. It is built by volunteering users from all over the world. GTFS mapper is a tool given a GTFS feed for a certain city and the osm data representing the same city would output a new feed with the same format of GTFS, but is produced using information and coordinates from the OSM data.

 

Suche mit regulären Ausdrücken

Christian Reitter, WS 2017/18, Projekt Homepage

This project is evaluating the design of a "search as you type" interface for special regular expressions on a large set of scanning data.

The extensive and complex database of perl compatible regular expressions of the Nmap project was chosen as a practical application for this search. Its database consists of about 11300 regular expressions that represent the bulk knowledge about varying binary response characteristics of a large number of network protocols and software implementations, allowing practical fingerprinting on various levels of software, vendor and devices. An additional meta-data syntax provided by the nmap probe format augmented with standardized Common Platform Enumeration (CPE) identifiers allows for the categorization of additional information, including the ability to extract target-specific information with the help of capturing groups within the regular expressions.

 

QLever SPARQL + TEXT UI

Julian Bürklin, Daniel Kemen, SS 2017, Projekt Homepage

QLever ist a full-featured SPARQL+Text engine which returns result tuples for given SPARQL queries. The old UI is very simplistic and hard to use. The goal of our project is to create a simple, powerful and intuitive UI for QLever which supports suggestions and auto-completions.

 

CompleteSearch

Evgeny Anatskiy, SS 2017, Projekt Homepage

The main goal was to create an easy-to-use web application, which would take a dataset (CSV, TSV), automatically determine a separator, validate the data (remove rows with a wrong syntax), define search facets, and save the file (pre-processing). Then, use the saved file as an input for the search engine CompleteSearch, which generates indices (post-processing).
CompleteSearch does all the work on performing the search in the uploaded dataset. The web application (this project) serves as a middle layer, which processes and corrects the user input, and sends it to a separate local CompleteSearch server.

 

Pseudo Database for Existing XML Files

Nishat Fariha, SS 2017, Projekt Homepage

The simulation tool SmartCalc.CTM (Fraunhofer ISE intern development) uses a set of XML files as its data source. These files contain data about Material properties of components of a photovoltaic module. The choice for XML files instead of a SQL database was motivated by the human readability and the possibility to give new files for new measured material properties to customers, who also run the software.

 

Completesearch

Julian Löffler, Rezart Quelibari, Matthias Urban, SS 2016, Projekt Homepage

The goal of this project is to set up a web app, where one can upload any CSV dataset, and then have a convenient search (with meaningful default settings), without having to set up anything oneself.

 

Deepdive

Louis Retter, Frank Gelhausen, SS 2016, Projekt Homepage

This project consisted of getting to know Deepdive aswell as finding out how well it performs and finding possible use cases. Deepdive is a data-managament system which can extract entities from a given text and predicts the probablility of entities engaged in a given relation using machine-learning. These predictions are based on user-defined features, not algorithms, which is the main advantage of using Deepdive over other systems.

  

Efficient Code for (De)Compression

Zhiwei Zhang, WS 2015/2016, Projekt Homepage

In this project I implemented the Elias-Gamma algorithm, the Elias-Delta algorithm, the Golomb algorithm, the Variable-Bytes algorithm and the mainly optimized decompression function of the Simple8b algorithm and at the same time compared them to find out the "best appropriate algorithm(s)" for the search engine Broccoli

 

Lexical Semantics

Max Lotstein SS 2015, Projekt Homepage

This project models the meanings of words based on how those words are used in a large corpus.The meaning-representation supports both equality and distance comparisons, as well as other operations from linear algebra. Some of these operations can be used for semantic comparisons and can thus be used for detection of related, and perhaps even synonymous, word pairs. Various tests of correspondence between human judgments of semantic similarity and the project’s output place it among similar systems, though not at the top..

 

A Mobile App for Kitchen Account Management

Simon Schonhart, Christian Reichenbach, WS 2014/2015, Projekt Homepage

Die osm.pbf Datei konnte mit Hilfe der Osmosis-library eingelesen werden. Entities, mit Tags (wie zum Beispiel: "shop=bakery"), welche in der zuvor erstellten Ontology File definiert wurden, werden herausgefiltert und in einem Index abgespeichert.

 

Entity-Component System

Jochen Kempfle, Markus Reher, WS 2013/2014, Projekt Homepage

The provided Entity-Component-System was implemented as the so called ESE-Project at the Chair of Algorithms and Data Structures at the University of Freiburg.

 

Wikification

Ragavan Natarajan, SS 2013, Projekt Homepage

Wikification is the process of identifying the important phrases in a document and linking each of them to appropriate articles on Wikipedia based on their context of occurrences. The important phrases in a document are also called keyphrases, somewhat similar to the term keyword, but unlike a keyword , a keyphrase can consist of one or more words. A wikifier is a software that performs the wikification of a document. One such software has been developed and made available here. This page discusses how it was developed from the ground-up. A more detailed report is available here.

  

Relation Extraction

Anton Stepan, Marius Bethge, 2012/2013, Projekt Homepage

Auf dieser Seite möchten wir kurz unseren Teil des Projektes vorstellen.

 

Multicriteria Multimodal Routeplanning

RobinTibor Schirrmeister, Simon Skilevic WS 2012, Projekt Homepage

The goal was to write a program that can perform shortest path queries in a hybrid network of public transportation lines and roads. These queries should use both the time of the path as well as the amount of transfers as criteria, thus "multi-criteria".
The program should also be able to create some basic visualization of the Dijkstra computation.

 

Transfer-pattern robustness

Eugen Sawin, Philip Stahl, Jonas Sternisko SS 2012, Projekt Homepage

This project extends to the development of an efficient route planner for public transportation networks, which is used to conduct experiments on the reliability of transfer patterns on dynamically modified networks.

Das Ziel des Projektes war, die Texte der Fachartikel für die semantische Suchmaschine Broccoli aufzubereiten. Dafür müssen bestimmte Entitäten, welche von Broccoli berücksichtigt werden sollen, in den Texten markiert werden.

 

Transit Routing

Mirko Brodesser, Dirk Kienle, Thomas Liebetraut, Kyanoush Seyed Yahosseini, SS 2011, Projekt Homepage

While it is quite easy to find paths in street networks, incorporating transit data can be quite challenging. There are bus stops that have to be considered, but the bus does not stop all the time, so it may be better to walk. The right bus stops have to be found to use the right bus or metro and when changing trains, the algorithm should wait for an appropriate period of time so that the user does not miss the bus.

 

Implementation of a new algorithm for the fast intersection of unions of sorted lists
