Wikipedia is a global crowdsourced encyclopedia that at time of writing is available in 287 languages. Wikidata is a likewise global crowdsourced knowledge base that provides shared facts to be used by Wikipedias. In the context of this research, we have developed an application and an underlying Application programming Interface (API) capable of monitoring realtime edit activity of all language versions of Wikipedia and Wikidata. this application allows us to easily analyze edits in order to answer questions such as \Bots vs. Wikipedians, who edits more?", \Which is the most anonymously edited Wikipedia?", or \Who are the bots and what do they edit?". To the best of our knowledge, this is the first time such an analysis was done for Wikidata and for really all Wikipedias|large and small. According to our results, all Wikipedias and Wikidata together are edited by about 50% bots and by about 23% anonymous users. Wikidata alone accounts for about 48% of the totally observed edits. If we do not consider Wikidata, i.e., if we only look at all Wikipedias, about 15% of all edits are made by bots and 26% of all edits are made by anonymous users. Overall, we found a stabilizing number of 274 active bots during our observation period. Our application is available publicly online at the URL http://***/, its code has been open-sourced under the Apache 2.0 license.

Augmented Reality (AR) technology enables continuous visual feedback and varied digital scenes on the real world. this paper presents AR-C&P, an AR-based tangible programming tool for young children. It allows children to create AR maze map with low-cost materials and plan the route by constructing tangible program sequences. Meanwhile, a variety of real-time visual feedback from the screen will be superimposed on the real scenes of the whole process. AR-C&P is intuitive and intriguing which could enrich children's creating experience, develops their cognitive developmental skills and helps children learn fundamental programming concepts. We conducted two experiments. the first experiment reveals the relationship between task completion and cognitive developmental skills. the second experiment reveals the effect of AR on learning programming.

We present a general framework for generating SQL query test cases using Constraint Logic programming. Given a database schema and a SQL view defined in terms of other views and schema tables, our technique generates automatically a set of finite domain constraints whose solutions constitute the test database instances. the soundness and correctness of the technique w.r.t. the semantics of Extended Relational Algebra is proved. Our setting has been implemented in an available tool covering a wide range of SQL queries, including views, subqueries, aggregates and set operations.

the paper presents the implementation of query execution system Qios. It serves as a lightware system for the manipulation of XML data. Qios employs the relational technology for query processing. the main aim in the implementation is to provide a querying system that is easy to use and does not require any additional knowledge about the internal representation of data. the system provides robust and simple solutions for many design problems. We aimed to simplify the internal structures of query processors rooted in the design of relational and object-relational query processors. We propose efficient internal data structures for the representation of queries during all phases of query execution. the query optimization is based on dynamic programming and uses beam search to reduce the time complexity. the data structure for storing queries provides efficient representation of queries during the optimization process and the simple means to explore plan caching. Finally, main memory indices can be created on-the-fly to support the evaluation of queries.

A correspondence between database tuples as causes for query answers in databases and tuple-based repairs of inconsistent databases with respect to denial constraints has already been established. In this work, answer-set programs that specify repairs of databases are used as a basis for solving computational and reasoning problems about causes. Here, causes are also introduced at the attribute level by appealing to a both null-based and attribute-based repair semantics. the corresponding repair programs are presented, and they are used as a basis for computation and reasoning about attribute-level causes.
