Conta-me Histórias / Tell me Stories
Conta-me Histórias (Tell me stories) is a tool that allows to automatically generate temporal summarization of news collections. through a friendly user interface that enables anyone to explore and revisit events in the past. To select relevant stories and temporal periods, we rely on YAKE!, a key-phrase extraction algorithm developed by our research team, and event detection methods made available by the research community. Additionally, we offer the engine as an open source package that can be extended to support different datasets or languages. The work described here stems from our participation at the Arquivo.pt 2018 competition, where we have been awarded the first prize.

YAKE! - Yet Another Keyword Extractor
YAKE! (Best Short Paper of ECIR'18) is a light-weight unsupervised automatic keyword extraction method which rests on text statistical features extracted from single documents to select the most important keywords of a text. Our system does not need to be trained on a particular set of documents, neither it depends on dictionaries, external-corpus, size of the text, language or domain. To demonstrate the merits and the significance of our proposal, we compare it against ten state-of-the-art unsupervised approaches (TF.IDF, KP-Miner, RAKE, TextRank, SingleRank, ExpandRank, TopicRank, TopicalPageRank, PositionRank and MultipartiteRank), and one supervised method (KEA). Experimental results carried out on top of twenty datasets show that our methods significantly outperform state-of-the-art methods under a number of collections of different sizes, languages or domains. YAKE is available through a demo, a Python package and an API.

GTE-Cluster and GTE-Rank
Here we provide two user interfaces so that the research community can test the GTE-Cluster and the GTE-Rank temporal search engine applications. In order to retrieve the query results, we rely on the recently launched Bing Search API (5000 transactions/month allowed) parameterized with the en-US market language parameter to retrieve 50 results per query. The proposed solutions are computationally efficient and can easily be tested online. Although the main motivation of our work is focused on queries with temporal nature, the implemented prototypes allow the execution of any query including non-temporal ones. Below is a detailed description of both user interfaces.

GTE-ClusterGTE-Cluster is a temporal clustering search engine, which offers the user two options: to return all the clusters (including the non-relevant) or to return only the relevant oCThe values that appear in front of the cluster, reflect the similarity value computed by the GTE similarity measure. Note that clusters with a similarity value < 0.35 are considered non-relevant and marked in red. In contrast, relevant clusters are marked in blue.

GTE-RankGTE-Rank is a temporal re-ranking search engine, which offers the user two options: to return all the web snippets (including those not having dates) or to return only the web snippets with relevant dates. The number in red color is the ranking position initially obtained by Bing search engine. The values in front of the snippet ID, reflect the ranking value computed by the GTE-Rank methodology.
