Semantic Search of Mobile Applications Using Word Embeddings

Authors: João Coelho, António Neto, Miguel Tavares, Carlos Coutinho, Ricardo Ribeiro, and Fernando Batista

Published in: OASIcs, Volume 94, 10th Symposium on Languages, Applications and Technologies (SLATE 2021)


Abstract
This paper proposes a set of approaches for the semantic search of mobile applications, based on their name and on the unstructured textual information contained in their description. The proposed approaches make use of word-level, character-level, and contextual word-embeddings that have been trained or fine-tuned using a dataset of about 500 thousand mobile apps, collected in the scope of this work. The proposed approaches have been evaluated using a public dataset that includes information about 43 thousand applications, and 56 manually annotated non-exact queries. Our results show that both character-level embeddings trained on our data, and fine-tuned RoBERTa models surpass the performance of the other existing retrieval strategies reported in the literature.

CodeVoting: protecting against malicious vote manipulation at the voter's PC

Authors: Rui Joaquim and Carlos Ribeiro

Published in: Dagstuhl Seminar Proceedings, Volume 7311, Frontiers of Electronic Voting (2008)


Abstract
Voting in uncontrolled environments, such as the Internet comes with a price, the price of having to trust in uncontrolled machines the collection of voter's vote. An uncontrolled machine, e.g. the voter's PC, may be infected with a virus or other malicious program that may try to change the voter's vote without her knowledge. Here we present CodeVoting, a technique to create a secure communication channel to a smart card that prevents vote manipulation by the voter's PC, while at the same time allows the use of any cryptographic voting protocol to cast the vote.
