    a time consuming and challenging task. Making use of freely available web data
    requires technical skills to work with APIs or to create a web scraping program
    specifically tailored to the task at hand. We present a light-weight
    alternative that employs the web data extraction language OXPath to harvest
    data to be added to an existing test collection from web resources. We
    demonstrate this by creating an extended version of GIRT4 called GIRT4-XT with
    additional metadata fields harvested via OXPath from the social sciences portal
    Sowiport. This allows the re-use of this collection for other evaluation
    purposes like bibliometrics-enhanced retrieval. The demonstrated method can be
    applied to a variety of similar scenarios and is not limited to extending
    existing collections but can also be used to create completely new ones with
    little effort.},

    @inproceedings{heck2013performing,
    abstract = {The combination of informetric analysis and information retrieval allows a twofold application. (1) While in-formetrics analysis is primarily used to gain insights into a scientific domain, it can be used to build recommen-dation or alternative ranking services. They are usually based on methods like co-occurrence or citation analyses. (2) Information retrieval and its decades-long tradition of rigorous evaluation using standard document corpora, predefined topics and relevance judgements can be used as a test bed for informetric analyses. We show a preliminary experiment on how both domains can be connected using the iSearch test collection, a standard information retrieval test collection derived from the open access arXiv.org preprint server. In this paper the aim is to draw a conclusion about the appropriateness of iSearch as a test bed for the evaluation of a retrieval or recommendation system that applies informetric methods to improve retrieval results for the user. Based on an interview study with physicists, bibliographic coupling and author-co-citation analysis, important authors for ten different research questions are identified. The results show that the analysed corpus includes these authors and their corresponding documents. This study is a first step towards a combination of retrieval evaluations and the evaluation of informetric analyses methods.},

In this study we do not focus on the retrieval performance of our system but on the relevance assessments and the inter-assessor reliability. To quantify the agreement we apply Fleiss’ Kappa and Krippendorff’s Alpha. When we compare these two statistical measures on average Kappa values were 0.37 and Alpha values 0.15. We use the two agreement measures to drop too unreliable assessments from our data set. When computing the differences between the unfiltered and the filtered data set we see a root mean square error between 0.02 and 0.12. We see this as a clear indicator that disagreement affects the reliability of retrieval evaluations. We suggest not to work with unfiltered results or to clearly document the disagreement rates.},

Vizgr.com offers basic visualization methods, like graphs, tag clouds, maps and time lines. But unlike normal data visualizations, these can be re-used, connected to each other and to web sites. We offer a simple opportunity to combine diverse data structures, such as geo-locations and networks, with each other by a mouse click. In an evaluation, we found that over 85 % of the participants were able to use and understand this technology without any training or explicit instructions.},

The services are: (1) a co-word analysis based query expansion mechanism and re-ranking via (2) Bradfordizing and (3) author centrality. The services are evaluated with relevance assessments conducted by 73 information science students. Since the students are neither information professionals nor domain experts the question of inter-rater agreement is taken into consideration. Two important implications emerge: (1) the inter-rater agreement rates were mainly fair to moderate and (2) after a data-cleaning step which erased the assessments with poor agreement rates the evaluation data shows that the three retrieval services returned disjoint but still relevant result sets.},

Beide Systeme setzen auf einen konsequenten Einsatz von Persistenten Identifikatoren (URN und DOI), was die Verkn\"upfung der durch da|ra registrierten Daten mit den Volltextdokumenten aus SSOAR sowie anderen Informationen aus den GESIS-Beständen erm\"oglicht. Zus\"atzlich wird durch den Einsatz von semantischen Technologien wie SKOS und RDF eine Verbindung zum Semantic Web hergestellt.},
