چکیده

In this paper we describe the KTIML team approach to RuleML 2015 Rule-based Recommender Systems for the Web of Data Challenge Track. The task is to estimate the top 5 movies for each user separately in a semantically enriched MovieLens 1M dataset. We have three results. Best is a domain specific method like "recommend for all users the same set of movies from Spielberg". Our contributions are domain independent data mining methods tailored for top-k which combine second order logic data aggregations and transformations of metadata, especially 5003 open data attributes and general GAP rules mining methods.

Ensemble-based Top-k Recommender System Considering Incomplete Data

Recommender systems have been widely used in e-commerce applications. They are a subclass of information filtering system, used to either predict whether a user will prefer an item (prediction problem) or identify a set of k items that will be user-interest (Top-k recommendation problem). Demanding sufficient ratings to make robust predictions and suggesting qualified recommendations are two si...

Fast Query Recommendation by Search

Query recommendation can not only effectively facilitate users to obtain their desired information but also increase ads’ click-through rates. This paper presents a general and highly efficient method for query recommendation. Given query sessions, we automatically generate many similar and dissimilar query-pairs as the prior knowledge. Then we learn a transformation from the prior knowledge to...

A Unifying View of Structural Induction and Computation Induction for Logic Programs

In the framework of Extended Prolog Execution K&S 86] a rule of Structural Induction is presented. For the induction step the new rule takes advantage of a Prolog program synthesized through Proof-Extraction techniques , and rests on extensive use of Negation as Failure Inference for exploiting the information contained in the extracted program. We describe how to synthesize Prolog procedures w...

Continuity of super- and sub-additive transformations of continuous functions

We prove a continuity inheritance property for super- and sub-additive transformations of non-negative continuous multivariate functions defined on the domain of all non-negative points and vanishing at the origin. As a corollary of this result we obtain that super- and sub-additive transformations of continuous aggregation functions are again continuous aggregation functions.

IPSSC: Integration of structured expert knowledge

This paper presents an effective implementation of data preprocessing methodology and data mining referring to integrate decision rules as part of manually written expert system (expert knowledge) with models inducted from data. The methods we have used are standard methods for data pre-processing, including techniques for handling missing data, feature construction, transformation and aggregat...
