Entity ranking using Wikipedia as a pivot

Rianne Kaptein, Pavel Serdyukov, Arjen De Vries, Jaap Kamps
2010 Proceedings of the 19th ACM international conference on Information and knowledge management - CIKM '10  
Wikipedia allows us to properly identify entities and some of their characteristics, and Wikipedia's elaborate category structure allows us to get a handle on the entity's type.  ...  Both Wikipedia's external links and the enriched Wikipedia entities with additional links to homepages are significantly better at finding primary web homepages than anchor text retrieval, which in turn  ...  Acknowledgments The created Entity Ranking topics test collection is available at http://staff.science.uva.nl/~kamps/effort/data.  ...

Using Anchor Text, Spam Filtering and Wikipedia for Web Search and Entity Ranking

Jaap Kamps, Rianne Kaptein, Marijn Koolen
2010 Text Retrieval Conference  
For the Entity Ranking Track, we use Wikipedia as a pivot to find relevant entities on the Web. Using category information to retrieve entities within Wikipedia leads to large improvements.  ...  Following the external links on Wikipedia pages to find the homepages of the entities in the ClueWeb collection, works better than searching an anchor text index, and combining the external links with  ...  When external links are used to find homepages, all Wikipedia results without external links to a page in the ClueWeb Category B collection are excluded from the ranking.  ...

Result Diversity and Entity Ranking Experiments: Anchors, Links, Text and Wikipedia

Rianne Kaptein, Marijn Koolen, Jaap Kamps
2009 Text Retrieval Conference  
Although the links between the Wikipedia entities and pages in the Clueweb collection are sparse, the precision of the existing links is very high.  ...  Using Wikipedia as a pivot results in large gains of P10 and NDCG when only primary pages are considered.  ...  Acknowledgments This research was supported by the Netherlands Organization for Scientific Research (NWO, grant # 612.066.513, 639.072.601, and 640.001.501).  ...

Extracting Named Entities and Synonyms from Wikipedia

Christian Bøhn, Kjetil Nørvåg
2010 2010 24th IEEE International Conference on Advanced Information Networking and Applications  
In this paper we describe how to use Wikipedia contents to automatically generate a dictionary of named entities and synonyms that are all referring to the same entity.  ...  Through an experimental evaluation we show that with our approach, we can find named entities and their synonyms with a high degree of accuracy.  ...  Acknowledgments The authors would like to thank Jon Atle Gulla for helpful feedback in the initial phase of this work, and George Tsatsaronis and Robert Neumayer for valuable help in improving the paper  ...

Classifying Image Galleries into a Taxonomy Using Metadata and Wikipedia [chapter]

Gerwin Kramer, Gosse Bouma, Dennis Hendriksen, Mathijs Homminga
2012 Lecture Notes in Computer Science  
The proposed method links textual gallery metadata to Wikipedia pages and categories.  ...  Entity extraction from metadata, entity ranking, and selection of categories is based on Wikipedia and does not require labeled training data.  ...  Find and score entity categories In this step, we try to find taxonomy categories for each entity by using its Wikipedia article.  ...

Are Human-Input Seeds Good Enough for Entity Set Expansion? Seeds Rewriting by Leveraging Wikipedia Semantic Knowledge [chapter]

Zhenyu Qi, Kang Liu, Jun Zhao
2012 Lecture Notes in Computer Science  
In our method, we leverage Wikipedia as a semantic knowledge to measure semantic relatedness and ambiguity of each seed.  ...  In this paper, we propose a novel method which can generate new, high-quality seeds and replace original, poor-quality ones.  ...  Are Human-Input Seeds Good Enough for Entity Set Expansion?  ...

Automatic Classification and Relationship Extraction for Multi-Lingual and Multi-Granular Events from Wikipedia

Daniel Hienert, Dennis Wegener, Heiko Paulheim
2012 International Semantic Web Conference  
As only a small amount of events is available in structured form in DBpedia, we extract these events with a rule-based approach from Wikipedia pages.  ...  In this paper we focus on three aspects: (1) extending our prior method for extracting events for a daily granularity, (2) the automatic classification of events and (3) finding relationships between events  ...  A part of these events includes categories which can be used to automatically build categories for about 70% of another language set on the basis of links to other Wikipedia/DBpedia entities.  ...

Focused Search in Books and Wikipedia: Categories, Links and Relevance Feedback [chapter]

Marijn Koolen, Rianne Kaptein, Jaap Kamps
2010 Lecture Notes in Computer Science  
Our findings for the Entity Ranking Track are in direct opposition of our Ad Hoc findings, namely, that the WordNet categories are more effective than the Wikipedia categories.  ...  In the Ad Hoc track we investigate focused link evidence, using only links from retrieved sections.  ...  In Section 5, we present our approach to the Entity Ranking Track. Finally, in Section 6, we discuss our findings and draw preliminary conclusions.  ...

Algorithms for Recollection of Search Terms Based on the Wikipedia Category Structure

Stijn Vandamme, Filip De Turck
2014 The Scientific World Journal  
In all our experiments, it takes 1 query on a category and on average 2.49 clicks, compared to 5.68 queries on the database's traditional text search engine for a 68.3% success probability or 6.01 queries  ...  This facilitates browsing and offers the users the possibility to look for named entities, even if they forgot their names.  ...  [17] use categories and the locality of links in Wikipedia for entity ranking. Hahn et al.  ...

Choosing Better Seeds for Entity Set Expansion by Leveraging Wikipedia Semantic Knowledge [chapter]

Zhenyu Qi, Kang Liu, Jun Zhao
2012 Communications in Computer and Information Science  
In our method, we leverage Wikipedia semantic knowledge to measure semantic relatedness and ambiguity of each seed.  ...  Entity Set Expansion, which refers to expanding a human-input seed set to a more complete set which belongs to the same semantic category, is an important task for open information extraction.  ...  For future work, we plan to use other semantic knowledge provided by Wikipedia like category hierarchy to help finding better seeds.  ...

ReFER: Effective Relevance Feedback for Entity Ranking [chapter]

Tereza Iofciu, Gianluca Demartini, Nick Craswell, Arjen P. de Vries
2011 Lecture Notes in Computer Science  
The most challenging general problem is to find relevant entities, of the correct type and characteristics, based on a free-text query that need not conform to any single ontology or category structure  ...  It employs the Wikipedia category structure, but augments that structure with 'smooth categories' to deal with the sparseness of the raw category information.  ...  We conclude that the proposed approach can be easily applied to any ER system in order to improve search effectiveness, and that the model performs well on the test collection we used.  ...

The Links Have It: Infobox Generation by Summarization over Linked Entities [article]

Kezun Zhang and Yanghua Xiao and Hanghang Tong and Haixun Wang and Wei Wang
2014 arXiv   pre-print
In this paper, instead of performing information extraction over unstructured natural language text directly, we focus on a rich set of semi-structured data in Wikipedia articles: linked entities.  ...  The idea of this paper is the following: If we can summarize the relationship between the entity and its linked entities, we immediately harvest some of the most important information about the entity.  ...  And different from above structural knowledge extraction methods, we use the structured information(linked entities, and categories) only in Wikipedia to extract knowledge(infobox).  ...
