We propose to apply the state of the art in interactive multimodal learning to visual lifelog exploration and search, using the Exquisitor system. Exquisitor is a highly scalable interactive learning system, which uses semantic features extracted from visual content and text to suggest relevant media items to the user, based on user relevance feedback on previously suggested items. Findings from our initial experiments indicate that interactive multimodal learning will likely work well for some LSC tasks, but also suggest some potential enhancements.","PeriodicalId":266823,"journal":{"name":"Proceedings of the ACM Workshop on Lifelog Search Challenge","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127455059","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}

This leads to many research in retrieval systems to be developed for lifelogging analysis. One of the most important factors of a successful lifelogging retrieval system is to enhance the user's ability to perform any queries, even arbitrary ones. This motivates our proposal of a retrieval system in which we focus on the two main properties. The first property is the ability to accurately annotate the lifelog dataset with metadata that is meaningful for the retrieving process. The second property focuses on a powerful user interface that supports a novice user to perform the retrieval efficiently.","PeriodicalId":266823,"journal":{"name":"Proceedings of the ACM Workshop on Lifelog Search Challenge","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125072074","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}

This work presents an interactive system aimed at improving the retrieval accuracy by query term suggestion. Besides, this system also assists users to refine the retrieval results by image similarity clustering. For recommending a list of candidate words, we extract visual concepts from images by using computer vision models, and then incorporate both official and additional concepts into our system using pre-trained word embedding, in which textual knowledge is inherent. We also purpose an intelligent mechanism for rapidly removing multiple irrelevant search results. For reaching out this purpose, we build kd-trees [1] offline for reducing the computational overhead and cluster similar images by nearest neighbor search in the embedding space. Whenever users exclude some irrelevant images, their nearest neighbors in the image embedding space are also removed. In this way, users can efficiently screen out the relevant results and purge the irrelevant ones, scanning over more retrieval results in a shorter period of time.","PeriodicalId":266823,"journal":{"name":"Proceedings of the ACM Workshop on Lifelog Search Challenge","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114474206","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}

This data can then be retrieved as an aside memory usable as well for people with memory issues or in daily life to be more efficient. This paper presents the retrieval system designed for the Lifelog Search Challenge 2019 competition. This retrieval system offers two search levels: a semantic one and an image-based one. The data used for the indexing for both levels (semantic data for the text-based method or combinations of HSV Histogram and BRIEF features for the example-based one) as well as the architecture of the overall system is described. Results from our experiments are promising. The text-based search engine has disparate results that strongly depend on the keywords used for the query. For the example search engine, the best features are composed of both HSV histogram and BRIEF features. Despite encouraging results, the processing time appears to be a limitation.","PeriodicalId":266823,"journal":{"name":"Proceedings of the ACM Workshop on Lifelog Search Challenge","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126705327","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}

However, searching and navigating these multi-source, multi-modal, and often unstructured data to extract useful information is still a relatively challenging task. Therefore, the LSC2019 competition has been organized so that researchers can demonstrate novel search engines, as well as exchange ideas and collaborate on these types of problems. We present in this paper our approach for supporting interactive searches of lifelog data by employing a new retrieval system calledVieLens, which is an interactive retrieval system enhanced by natural language processing techniques to extend and improve search results mainly in the context of a user's activities in their daily life.","PeriodicalId":266823,"journal":{"name":"Proceedings of the ACM Workshop on Lifelog Search Challenge","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117188526","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}

Such data is special in the context of multimedia, not only because of its close personal relationship with its originator, but also because of its diverse multimodality and its composition from structured, semi-structured, and unstructured data. This diversity poses retrieval challenges that are unique to lifelog data but which also have implications for retrieval activity in other multimedia domains. In this paper, we present the extensions made to the vitrivr open-source multimedia retrieval stack, in order to address some of these unique lifelogging challenges. For the participation to the 2019 Lifelog Search Challenge (LSC), we have extended vitrivr with the capability to process Boolean query expressions alongside content-based query descriptions in order to leverage the structural diversity inherent to lifelog data.","PeriodicalId":266823,"journal":{"name":"Proceedings of the ACM Workshop on Lifelog Search Challenge","volume":"23 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132969178","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}
