The World Wide Web is moving from a of hyper-linked Documents to linked Data. Thanks the Semantic spread and more recent Linked Open Data (LOD) initiative, vast amount RDF data have been published in freely accessible datasets. These datasets are connected with each other form so called cloud. As today, there tons available Data, but only few applications really exploit their potential power. In this paper we show how these can successfully be used develop recommender system (RS) that relies...

Linked Open Data has been recognized as a valuable source for background information in many data mining and retrieval tasks. However, most of the existing tools require features propositional form, i.e., vector nominal or numerical associated with an instance, while Li nked sources are graphs by nature. In this paper, we present RDF2Vec, approach that uses language modeling approaches unsupervised feature extraction from sequences words, adapts them to RDF graphs. We generate leveraging...

This work takes a critical stance on previous studies concerning fairness evaluation in Large Language Model (LLM)-based recommender systems, which have primarily assessed consumer by comparing recommendation lists generated with and without sensitive user attributes. Such approaches implicitly treat discrepancies recommended items as biases, overlooking whether these changes might stem from genuine personalization aligned true preferences of users. Moreover, earlier typically address single...

The advent of the Linked Open Data (LOD) initiative gave birth to a variety open knowledge bases freely accessible on Web. They provide valuable source information that can improve conventional recommender systems, if properly exploited. In this paper we present SPrank, novel hybrid recommendation algorithm able compute top-N item recommendations from implicit feedback exploiting available in so called Web Data. We leverage DBpedia, well-known base LOD compass, extract semantic path-based...

The Web has moved, slowly but steadily, from a collection of documents towards structured data. Knowledge graphs have then emerged as way representing the knowledge encoded in such data well tool to reason on them order extract new and implicit information. are currently used, for example, explain search results, explore spaces, semantically enrich textual documents, or feed knowledge-intensive applications recommender systems. In this work, we describe how create exploit graph supply hybrid...

In most real-world scenarios, the ultimate goal of recommender system applications is to suggest a short ranked list items, namely top- N recommendations, that will appeal end user. Often, problem computing recommendations mainly tackled with two-step approach. The focuses first on predicting unknown ratings, which are eventually used generate recommendation list. Actually, task can be directly seen as ranking where main not accurately predict ratings but find best-ranked items recommend....

Recommender Systems have shown to be an effective way alleviate the over-choice problem and provide accurate tailored recommendations. However, impressive number of proposed recommendation algorithms, splitting strategies, evaluation protocols, metrics, tasks, has made rigorous experimental particularly challenging. Puzzled frustrated by continuous recreation appropriate benchmarks, pipelines, hyperparameter optimization, procedures, we developed exhaustive framework address such needs....

Matchmaking arises when supply and demand meet in an electronic marketplace, or agents search for a web service to perform some task, even recruiting agencies match curricula job profiles. In such open environments, the objective of matchmaking process is discover best available offers given request.

Providing very accurate recommendations to end users has been nowadays recognized be just one of the main tasks a recommender systems must able perform. While predicting relevant suggestions, attention needs paid their diversification in order avoid monotony recommendation. In this paper we focus on modeling users' inclination toward selecting diverse items, where diversity is computed by means content-based item attributes. We then exploit such present novel approach re-rank list Top-N...

Research on recommender systems algorithms, like other areas of applied machine learning, is largely dominated by efforts to improve the state-of-the-art, typically in terms accuracy measures. Several recent research works however indicate that reported improvements over years sometimes "don't add up", and methods were published several ago often outperform latest models when evaluated independently. Different factors contribute this phenomenon, including some researchers probably only...
