However, this combination and configuration is a manual procedure and has to be repeated for different consumers' or market requirements regarding matching quality. In this paper, we propose our framework MatchBox, which supports a broker in reusing existing matching approaches and combining them in a model-driven way based on a reconfigurable model of the matching process.Using this reconfigurable model, MatchBox takes care of control and data flow between matching approaches and executes the modeled processes automatically.As a case study, we integrated eleven matchers into MatchBox to demonstrate that it remains flexibility and reduces effort for a broker at the same time.}}, author = {{Platenius, Marie Christin and Arifulina, Svetlana and Schäfer, Wilhelm}}, booktitle = {{Proceedings of the 18th International ACM Sigsoft Symposium on Component-Based Software Engineering (CBSE'15)}}, pages = {{75--84}}, title = {{{MatchBox: A Framework for Dynamic Configuration of Service Matching Processes}}}, doi = {{10.1145/2737166.2737174}}, year = {{2015}}, } @inproceedings{1141, author = {{Stuß, Valentina and Geierhos, Michaela}}, booktitle = {{DHd 2015: Book of Abstracts}}, location = {{Graz, Austria}}, pages = {{239--243}}, publisher = {{ZIM-ACDH}}, title = {{{Identifikation kognitiver Effekte in Online-Bewertungen}}}, year = {{2015}}, } @inproceedings{1142, author = {{Geierhos, Michaela and Bäumer, Frederik Simon}}, booktitle = {{DHd 2015: Book of Abstracts}}, location = {{Graz, Austria}}, pages = {{69--72}}, publisher = {{ZIM-ACDH}}, title = {{{Erfahrungsberichte aus zweiter Hand: Erkenntnisse über die Autorschaft von Arztbewertungen in Online-Portalen}}}, year = {{2015}}, } @article{1143, abstract = {{Der Erfahrungsaustausch zwischen Patienten findet heutzutage zunehmend im Internet statt.

Our corpus consists of the digitised biographical lexicon “Neue Deutsche Biographie (NDB)”, roughly 21.000 biographies in 25 volumes in print since 1953. We developed local grammars and suitable dictionaries to describe interpersonal relations and applied them to the corpus with Unitex 3.1. The local grammars were designed to integrate existing TEI-XML structures in the corpus. Using the ability of local grammars in Unitex to act as transducers we were able to produce XML-Tags and encode semantic information. Based on grammars for personal names and places we described interpersonal relations like to study, predecessors and successors as well as friends and circles. Afterwards we identified persons (as given in the authority file or index). Finally we displayed relations on our website in an interactive and dynamic way.

The reviews and ratings on these platforms are valuable sources of information for patient opinion mining. In this paper, we have tackled three issues that come along with inconsistency analysis on PRWs: (1) Natural language processing of user-generated reviews, (2) the disagreement in polarity of review text and its corresponding numerical ratings (individual inconsistency) and (3) the differences in patients’ rating behavior for the same service category (e.g. ‘treatment’) expressed by varying grades on the entire data set (collective inconsistency). Thus, the basic idea is first to identify relevant opinion phrases that describe service categories and to determine their polarity. Subsequently, the particular phrase has to be assigned to its corresponding numerical rating category before checking the (dis-)agreement of polarity values. For this purpose, several local grammars for the pattern-based analysis as well as domain-specific dictionaries for the recognition of entities, aspects and polarity were applied on 593,633 physician reviews from both German PRWs jameda.de and docinsider.de. Furthermore, our research contributes to content quality improvement of PRWs because we provide a technique to detect inconsistent reviews that could be ignored for the computation of average ratings.}}, author = {{Geierhos, Michaela and Bäumer, Frederik Simon and Schulze, Sabine and Stuß, Valentina}}, booktitle = {{ECIS 2015 Completed Research Papers}}, isbn = {{9783000502842}}, location = {{Münster, Germany}}, publisher = {{Elsevier}}, title = {{{"I grade what I get but write what I think."

People can directly access physician rating websites via web browsers or use any search engine to find physician reviews and ratings filtered by location resp. specialty. However, sometimes keyword search does not meet user needs because of the disagreement of users’ common terms queries for symptoms and the widespread medical terminology. In this paper, we present the prototype of a specialised search engine that overcomes this by indexing user-generated content (i.e., review texts) for physician discovery and provides automatic suggestions as well as an appropriate visualisation. On the one hand, we consider the available numeric physician ratings as sorting criterion for the ranking of query results. Furthermore, we extended existing ranking algorithms with respect to domain-specific types and physicians ratings on the other hand.
