The new features for the Lifelog Search Challenge 2020 include support for timeline browsing, search functionality for finding positive examples, and significant interface improvements.

In the Lifelog Search Challenge (LSC), multimedia retrieval systems compete in finding events based on descriptions containing hints about structured, semi-structured an unstructured data. In this paper, we present the multimedia retrieval system vitrivr with a focus on the changes and additions made based on the new dataset, and our successful participation at LSC 2019. Specifically, we show how the new dataset can be used for retrieval in different modalities without sacrificing efficiency, describe two recent additions, temporal scoring and staged querying, and discuss the deep learning methods used to enrich the dataset.","PeriodicalId":340585,"journal":{"name":"Proceedings of the Third Annual Workshop on Lifelog Search Challenge","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129558106","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}

As lifelog is usually disorganized with multi-modal information (even noisy sometimes), an interactive search engine is crucial for users to review and explore their lifelog. Unlike traditional search engines, lifelog search includes multi-modality information of images, text and other data from sensors, which brings challenges to data arrangement and search. Accordingly, users' information need is also multi-level. Hence, a single interaction mechanism may not be able to satisfy users' requirements. As the data set is highly personalized, interaction and feedback from users should also be considered in the search engine. Therefore, in this paper we present an interactive multi-modality lifelog search engine to help users manage and find lifelog data. To this end, lifelog data is clustered and processed in multi-level processing. Then, we build an interactive search engine, includingtext as query, image as query, andtimeline view modules. Besides, the system is able to adopt user feedback mechanisms in multi-round queries. Our system shows promising experimental results on LSC'20 dataset and development topics. The text-based search module gives correct results on more than 60% of the development topics at LSC'20.","PeriodicalId":340585,"journal":{"name":"Proceedings of the Third Annual Workshop on Lifelog Search Challenge","volume":"777 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130212565","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}
