Retrieving musical records from a corpus of Information, using an audio input as a query is not an easy task. Various approaches try to solve the problem modelling the query and the corpus of Information as an array of hashes calculated from the chroma features of the audio input. Scope of this talk is to introduce a novel approach in calculating such hashes, considering the intervals of the most intense pitches of sequential chroma vectors. Building on the theoretical introduction, a prototype will show you this approach in action with Apache Solr with a sample dataset and the benefits of positional queries. Challenges and future works will follow up as conclusive considerations.]]>

Every team working on information retrieval software struggles with the task of evaluating how well their system performs in terms of search quality(currently and historically). Evaluating search quality is important both to understand and size the improvement or regression of your search application across the development cycles, and to communicate such progress to relevant stakeholders. In the industry, and especially in the open source community, the landscape is quite fragmented: such requirements are often achieved using ad-hoc partial solutions that each time require a considerable amount of development and customization effort. To provide a standard, unified and approachable technology, we developed the Rated Ranking Evaluator (RRE), an open source tool for evaluating and measuring the search quality of a given search infrastructure. RRE is modular, compatible with multiple search technologies and easy to extend.]]>

Every search engineer ordinarily struggles with the task of evaluating how well a search engine is performing. Improving the correctness and effectiveness of a search system requires a set of tools which help measuring the direction where the system is going. The talk will describe the Rated Ranking Evaluator from a developer perspective. RRE is an open source search quality evaluation tool, that could be used for producing a set of deliverable reports and that could be integrated within a continuous integration infrastructure.]]>
