[{"abstract":[{"lang":"eng","text":"Large intermediate results can cause join queries to run unexpectedly long. This problem is particularly common for analytical queries, which aggregate data over many tables to produce a comparatively small final output, and queries on graph data, where intermediate results blow up quickly. Recent work inspired by Yannakakis’ algorithm approaches this by modifying the query engine to avoid materializing unnecessary tuples. However, this requires significant changes to the core of the system, which is not feasible in many situations such as cloud environments or proprietary systems.\r\nIn this work, we propose a flexible approach for optimizing long-running join queries from the outside of the DBMS. Rewriting-based realizations of Yannakakis’ algorithm suffer from inherent overhead due to the creation of intermediate tables. Thus, we present an approach for detecting and targeting queries which would benefit from a Yannakakis-style optimization. We introduce a new benchmark combining 5 standard benchmarks and augmenting them with additional instances, which provides a sufficient size and diversity for a machine learning based solution. On PostgreSQL, DuckDB and SparkSQL, slowdowns on queries where the rewriting is counterproductive are mostly avoided, as opposed to a naïve application of the rewriting, and we observe significant improvements in end-to-end runtimes over standard query execution and unconditional rewriting."}],"status":"public","publication":"Proceedings of the 28th International Workshop on Design, Optimization, Languages and Analytical Processing of Big Data (DOLAP 2026)","type":"conference","keyword":["Join Queries","Acyclic Queries","Query Processing"],"language":[{"iso":"eng"}],"_id":"65178","department":[{"_id":"888"}],"user_id":"114410","year":"2026","place":"Tampere, Finland","citation":{"ama":"Böhm D, Gottlob G, Lanzinger M, et al.

For this reason, this study focuses on the development of a new forming technology for Ti-6Al-4V sheet metal. It is based on combination of solution treatment by resistive heating with rapid tool-based quenching and subsequent annealing. This new “TISTRAQ” process is comparable with press-hardening already known for steels and hot die quenching known for aluminium alloys. One of the main influencing factors for this process is the heat transfer coefficient (HTC). It is an important driver for adjustment of basic parameters, as selection of tool material or the forming speed but also plays an important role while elaborating temperature distribution in the numerical model. Therefore, a new and unique test rig was developed to determine the HTC and to perform tool-based heat treatment at specimen level under laboratory conditions. The test rig was used to investigate the influence of the titanium-tool-lubricant system on HTC and cooling rate. Further the effect of heat treatment in the test rig and tool-based quenching on microstructure and mechanical properties was studied. To improve the prediction of the temperature distribution of the titanium during cooling, the HTC was integrated into the numerical process simulation"}],"status":"public","_id":"49430","user_id":"72351","department":[{"_id":"9"},{"_id":"321"},{"_id":"149"}],"keyword":["Interfacial heat transfer coefficient","Ti-6Al-4V","nonisothermal forming","thermomechanical processing","TISTRAQ process"],"language":[{"iso":"eng"}]},{"keyword":["Ti-6Al-4V","thermomechanical processing","resistive heating","quench-forming","process parameter-microstructure-properties relationship"],"language":[{"iso":"eng"}],"_id":"49437","department":[{"_id":"9"},{"_id":"321"},{"_id":"149"}],"user_id":"72351","abstract":[{"lang":"eng","text":"The phase and TTT diagrams of the Ti-6Al-4V system allow the development of a new forming process for a more energy- and materialefficient production of sheet metal parts. This new “TISTRAQ” process is composed of two steps. In terms of process technology, the first step is comparable to a direct press-hardening process already well known for steels. In this step, the Ti-6Al-4V sheet material is resistively heated to a temperature below β-transus Tβ and, after a very short holding time, simultaneously formed and quenched by use of water cooled tools. Thereby, the β phase undergoes a martensitic transformation. The second step is a subsequent short-time annealing, which leads to a hardening of the material. In this work, a new test rig using resistive heating technique was used in order to produce\r\ndifferent solution treated and tool quenched (STQ) and subsequently annealed (STA) states. In this paper, the effects of heating rate, solution treatment temperature and holding time on microstructure and mechanical properties are addressed. For the characterisation, tensile testing and scanning electron microscopy were used. By the systematic variation of applied processing parameters, dominating effects on microstructure and mechanical properties were evaluated. For example, the solution treatment temperature was found to have a significant effect on microstructural features and characteristic strength and strain values. The obtained results reveal a high potential for future technical applications."}],"status":"public","publication":"IOM3.

One of the most important factors of a property’s value is its location. However, creating accurate quantifications of location remains a challenge. While traditional approaches rely on Geographical Information Systems (GIS), recently unstructured data in form of images was incorporated in the appraisal process, but text data remains an untapped reservoir. Our study shows that using text data in form of geolocated Wikipedia articles can increase predictive performance over traditional GIS-based methods by 8.2% in spatial out-of-sample validation. A framework to automatically extract geographically weighted vector representations for text is established and used alongside traditional structural housing features to make predictions and to uncover local patterns on sale price for real estate transactions between 2015 and 2020 in Allegheny County, Pennsylvania."}],"status":"public","_id":"27507","department":[{"_id":"195"}],"user_id":"77066","keyword":["Real Estate Appraisal","Text Regression","Natural Language Processing (NLP)","Location Intelligence","Wikipedia"],"language":[{"iso":"eng"}]},{"language":[{"iso":"eng"}],"ddc":["006"],"keyword":["Sentiment analysis","Natural language processing","Aspect phrase extraction"],"file":[{"access_level":"closed","file_name":"Kersting & Bäumer (2022), Kersting2022.pdf","file_id":"34172","file_size":155548,"creator":"jkers","date_created":"2022-12-01T13:39:48Z","date_updated":"2022-12-01T13:39:48Z","relation":"main_file","success":1,"content_type":"application/pdf"}],"abstract":[{"text":"This paper aims at discussing past limitations set in sentiment analysis research regarding explicit and implicit mentions of opinions.

Users consume billions of terabytes a day while surfing on news sites or blogs, posting on social media sites, and sending chat messages around the globe. While content is heterogeneous, the dominant form of web content is text. There are situations where more diversity needs to be introduced into text content, for example, to reuse it on websites or to allow a chatbot to base its models on the information conveyed rather than of the language used. In order to achieve this, paraphrasing techniques have been developed: One example is Text spinning, a technique that automatically paraphrases text while leaving the intent intact. This makes it easier to reuse content, or to change the language generated by the bot more human. One method for modifying texts is a combination of translation and back-translation. This paper presents NATTS, a naive approach that uses transformer-based translation models to create diversified text, combining translation steps in one model.

In order to achieve high quality without a long time delay, it makes sense to inspect the work pieces so that defective work pieces can be sorted out right at the beginning of the process. At the same time, the evaluation unit should come close the perception of the human eye regarding detection of defects in surfaces. Such defects often manifest themselves by a deviation of the existing structure. The only restriction should be that only matt surfaces should be considered here. Therefore in this work, different classification and image processing algorithms are applied to surface data to identify possible surface damages. For this purpose, the Gabor filter and the FST (Fused Structure and Texture) features generated with it, as well as the salience metric are used on the image processing side. On the classification side, however, deep neural networks, Convolutional Neural Networks (CNN), and autoencoders are used to make a decision. A distinction is also made between training using class labels and without. It turns out later that the salience metric are best performed by CNN. On the other hand, if there is no labeled training data available, a novelty classification can easily be achieved by using autoencoders as well as the salience metric and some filters.","lang":"eng"}],"status":"public"},{"ddc":["000"],"keyword":["Ideational impact","citation classification","academic recommender systems","natural language processing","deep learning","cumulative tradition"],"language":[{"iso":"eng"}],"abstract":[{"text":"Ideational impact refers to the uptake of a paper's ideas and concepts by subsequent research. It is defined in stark contrast to total citation impact, a measure predominantly used in research evaluation that assumes that all citations are equal. Understanding ideational impact is critical for evaluating research impact and understanding how scientific disciplines build a cumulative tradition. Research has only recently developed automated citation classification techniques to distinguish between different types of citations and generally does not emphasize the conceptual content of the citations and its ideational impact. To address this problem, we develop Deep Content-enriched Ideational Impact Classification (Deep-CENIC) as the first automated approach for ideational impact classification to support researchers' literature search practices. We evaluate Deep-CENIC on 1,256 papers citing 24 information systems review articles from the IT business value domain. We show that Deep-CENIC significantly outperforms state-of-the-art benchmark models.

In this paper we dissect the gains of the time-domain audio separation network (TasNet) approach by gradually replacing components of an utterance-level permutation invariant training (u-PIT) based separation system in the frequency domain until the TasNet system is reached, thus blending components of frequency domain approaches with those of time domain approaches. Some of the intermediate variants achieve comparable signal-to-distortion ratio (SDR) gains to TasNet, but retain the advantage of frequency domain processing: compatibility with classic signal processing tools such as frequency-domain beamforming and the human interpretability of the masks. Furthermore, we show that the scale invariant signal-to-distortion ratio (si-SDR) criterion used as loss function in TasNet is related to a logarithmic mean square error criterion and that it is this criterion which contributes most reliable to the performance advantage of TasNet. Finally, we critically assess which gains in a noise-free single channel environment generalize to more realistic reverberant conditions.","lang":"eng"}],"file":[{"file_size":3871374,"file_id":"20699","file_name":"ms.pdf","access_level":"closed","date_updated":"2020-12-11T12:36:37Z","creator":"jensheit","date_created":"2020-12-11T12:36:37Z","success":1,"relation":"main_file","content_type":"application/pdf"}],"keyword":["voice activity detection","speech activity detection","neural network","statistical speech processing"],"ddc":["000"],"language":[{"iso":"eng"}],"quality_controlled":"1","year":"2020","date_created":"2020-11-25T14:56:53Z","title":"Demystifying TasNet: A Dissecting Approach","type":"conference","status":"public","_id":"20504","project":[{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"department":[{"_id":"54"}],"user_id":"40767","file_date_updated":"2020-12-11T12:36:37Z","has_accepted_license":"1","citation":{"short":"J.

The former employs sophisticated signal processing to track the noise and speech energies and is meant to support the case for a resource efficient, unsupervised signal processing approach.\r\nThe latter introduces a recurrent network layer that operates on short segments of the input speech to do temporal smoothing in the presence of non-stationary noise. The systems are tested on the Fearless Steps challenge database, which consists of the transmission data from the Apollo-11 space mission.\r\nThe statistical SAD  achieves comparable detection performance to earlier proposed neural network based SADs, while the neural network based approach leads to a decision cost function of 1.07% on the evaluation set of the 2020 Fearless Steps Challenge, which sets a new state of the art."}],"status":"public","file":[{"creator":"jensheit","date_created":"2020-12-11T12:33:04Z","date_updated":"2020-12-11T12:33:04Z","file_name":"ms.pdf","access_level":"closed","file_id":"20697","file_size":998706,"content_type":"application/pdf","relation":"main_file","success":1}]},{"publication":"encyclopedia.pub","type":"encyclopedia_article","status":"public","department":[{"_id":"36"},{"_id":"1"},{"_id":"579"}],"user_id":"42496","_id":"8312","project":[{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Project Area B","_id":"3"},{"name":"SFB 901 - Subproject B1","_id":"9"}],"language":[{"iso":"eng"}],"keyword":["OTF Computing","Natural Language Processing","Requirements Engineering"],"quality_controlled":"1","publication_status":"published","citation":{"chicago":"Bäumer, Frederik Simon, and Michaela Geierhos. “Requirements Engineering in OTF-Computing.” In <i>Encyclopedia.Pub</i>.

With the goal set on an autonomous multi-movement prosthesis capable of performing training and classification of an amputee’s EMG signals, the focus of this paper lies in the acceleration of the embedded signal processing chain. We present two Xilinx Zynq-based architectures for accelerating two inherently different high density EMG-based control algorithms. The first hardware accelerated design achieves speed-ups of up to 4.8 over the software-only solution, allowing for a processing delay lower than the sample period of 1 ms. The second system achieved a speed-up of 5.5 over the software-only version and operates at a still satisfactory low processing delay of up to 15 ms while providing a higher reliability and robustness against electrode shift and noisy channels."}],"user_id":"398","department":[{"_id":"78"}],"_id":"11950","language":[{"iso":"eng"}],"keyword":["High density electromyography","FPGA acceleration","Medical signal processing","Pattern recognition","Prosthetics"]},{"type":"journal_article","status":"public","_id":"2331","project":[{"_id":"1","name":"SFB 901"},{"name":"SFB 901 - Project Area B","_id":"3"},{"name":"SFB 901 - Subproject B1","_id":"9"}],"department":[{"_id":"36"},{"_id":"1"},{"_id":"579"}],"user_id":"477","article_type":"original","file_date_updated":"2018-11-02T15:16:29Z","publication_identifier":{"issn":["2005-4238"],"eissn":["2207-6360"]},"has_accepted_license":"1","publication_status":"published","intvolume":"       112","page":"123-136","citation":{"ama":"Kim Y, Lee S, Dollmann M, Geierhos M.
