Users who actively enter, review and revise data on Wikidata are assisted by a property suggesting system which provides users with properties that might also be applicable to a given item. We argue that evaluating and subsequently improving this recommendation mechanism and hence, assisting users, can directly contribute to an even more integrated, consistent and extensive knowledge base serving a huge variety of applications. However, the quality and usefulness of such recommendations has not been evaluated yet. In this work, we provide the first evaluation of different approaches aiming to provide users with property recommendations in the process of curating information on Wikidata. We compare the approach currently facilitated on Wikidata with two state-of-the-art recommendation approaches stemming from the field of RDF recommender systems and collaborative information systems. Further, we also evaluate hybrid recommender systems combining these approaches. Our evaluations show that the current recommendation algorithm works well in regards to recall and precision, reaching a recall@7 of 79.71% and a precision@7 of 27.97%. We also find that generally, incorporating contextual as well as classifying information into the computation of property recommendations can further improve its performance significantly.","PeriodicalId":297748,"journal":{"name":"Proceedings of the 12th International Symposium on Open Collaboration","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115710231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some of these goals, such as the lookup of facts, can be effectively supported by search functions. However, for other use cases such as researching an unfamiliar topic, users need to rely on the links to connect articles. In this paper, we investigate the state of navigability in the article networks of eight language versions of Wikipedia. We find that, when taking all links of articles into account, all language versions enable mutual reachability for almost all articles. However, previous research has shown that visitors of Wikipedia focus most of their attention on the areas located close to the top. We therefore investigate different restricted navigational views that users could have when looking at articles. We find that restricting the view of articles strongly limits the navigability of the resulting networks and impedes navigation. Based on this analysis we then propose a link recommendation method to augment the link network to improve navigability in the network. Our approach selects links from a less restricted view of the article and proposes to move these links into more visible sections. The recommended links are therefore relevant for the article. Our results are relevant for researchers interested in the navigability of Wikipedia and open up new avenues for link recommendations in Wikipedia editing.","PeriodicalId":297748,"journal":{"name":"Proceedings of the 12th International Symposium on Open Collaboration","volume":"171 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114627146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
