Learning Semantic Query Suggestions [chapter]

Edgar Meij, Marc Bron, Laura Hollink, Bouke Huurnink, Maarten de Rijke
2009 Lecture Notes in Computer Science  
An important application of semantic web technology is recognizing human-defined concepts in text. Query transformation is a strategy often used in search engines to derive queries that are able to return more useful search results than the original query and most popular search engines provide facilities that let users complete, specify, or reformulate their queries. We study the problem of semantic query suggestion, a special type of query transformation based on identifying semantic concepts

We use a feature-based approach in conjunction with supervised machine learning, augmenting term-based features with search history-based and concept-specific features. We apply our method to the task of linking queries from real-world query logs (the transaction logs of the Netherlands Institute for Sound and Vision) to the DBpedia knowledge base. We evaluate the utility of different machine learning algorithms, features, and feature types in identifying semantic concepts using a manually developed test bed and show significant improvements over an already high baseline. The resources developed for this paper, i.e., queries, human assessments, and extracted features, are available for download.

Term Selection and Query Operations for Video Retrieval [chapter]

Bouke Huurnink, Maarten de Rijke
2007 Lecture Notes in Computer Science  
We investigate the influence of term selection and query operations on the text retrieval component of video search. Our main finding is that the greatest gain is to be found in the combination of character n-grams, stemmed text, and proximity terms.

Linking Archives Using Document Enrichment and Term Selection [chapter]

Marc Bron, Bouke Huurnink, Maarten de Rijke
2011 Lecture Notes in Computer Science  
News, multimedia and cultural heritage archives are increasingly offering opportunities to create connections between their collections. We consider the task of linking archives: connecting an item in one archive to one or more items in other, often complementary archives. We focus on a specific instance of the task: linking items with a rich textual representation in a news archive to items with sparse annotations in a multimedia archive, where items should be linked if they describe the same

We find that the difference in textual richness of annotations presents a challenge and investigate two approaches: (i) to enrich sparsely annotated items with textually rich content; and (ii) to reduce rich news archive items using term selection. We demonstrate the positive impact of both approaches on linking to same events and linking to related events.

AVResearcher: Exploring Audiovisual Metadata

Bouke Huurnink, Amit Bronner, Marc Bron, Jasmijn van Gorp, Bart de Goede, Justin van Wees
2013 Dutch-Belgian Workshop on Information Retrieval  
In this demonstration we present AVResearcher, a prototype aimed at allowing media researchers to explore metadata associated with large numbers of audiovisual broadcasts. It allows them to compare and contrast the characteristics of search results for two topics, across time and in terms of content. Broadcasts can be searched and compared not only on the basis of traditional catalog descriptions, but also in terms of spoken content (subtitles), and social chatter (tweets associated with

Exploiting redundancy in cross-channel video retrieval

Bouke Huurnink, Maarten de Rijke
2007 Proceedings of the international workshop on Workshop on multimedia information retrieval - MIR '07  
Video producers, in telling a news story, tend to repeat important visual and speech material multiple times in adjacent shots, thus creating a certain level of redundancy. We describe this phenomenon, and use it to develop a framework to incorporate redundancy for cross-channel retrieval of visual items using speech. Testing our models in a series of retrieval experiments, we find that incorporating the fact that information occurs redundantly into cross-channel retrieval leads to significant improvements in retrieval performance.

Validating Query Simulators: An Experiment Using Commercial Searches and Purchases [chapter]

Bouke Huurnink, Katja Hofmann, Maarten de Rijke, Marc Bron
2010 Lecture Notes in Computer Science  
We design and validate simulators for generating queries and relevance judgments for retrieval system evaluation. We develop a simulation framework that incorporates existing and new simulation strategies. To validate a simulator, we assess whether evaluation using its output data ranks retrieval systems in the same way as evaluation using real-world data. The real-world data is obtained using logged commercial searches and associated purchase decisions. While no simulator reproduces an ideal

Incorporating knowledge about document structure in the query generation process helps create more realistic simulators.

In this paper we present SocialZap, a multimedia search engine that finds the most interesting fragments, zap points, in a television broadcast based on microblog posts and socially tagged photos. The main novelty of SocialZap is the fully-automatic transfer of the learned viewers interest from textual posts to the visual channel, without the need for any manual effort in the process. Once SocialZap finds the zap points, users can easily browse through a television broadcast and directly watch
