The future financial prospects of companies can be estimated through the aggregation of sentiment over a period of time.

In certain instances, news text may refer to groups or collections of companies, for example "The Automotive Sector" or "The Russell Group of Universities". Widely available named entity dictionaries will not recognize these groups of companies, and consequently, it may not be possible to assign sentiment attributed to these groups of companies to their individual members. This paper describes a method for identifying groups of companies, which for the purposes of this paper will be known as "Collective Entities". The described method is corpus based: it uses linguistic patterns to identify Collective Entity Names, their members and their natural relations with other Collective Entities. The described methodology contains the following steps: 1. Identify and validate seed extraction patterns, 2. Expand seed patterns, 3. Extract and validate Collective Named Entities, 4. Extract related Collective Named Entities, 5. Construct and populate an Ontology and 6.

But plain filesystems were used for years, and are still used, to store information, commonly in files of heterogeneous formats that are organized in directory trees. This approach is a very flexible and natural way to create hierarchical organized structures of documents. We can devise a formal notation to describe a filesystem tree structure, similar to a grammar, assuming that filenames can be considered terminal symbols, and directory names non-terminal symbols. This specification would allow to derive correct language sentences (combination of terminal symbols) and to associate semantic actions, that can produce arbitrary side effects, to each valid sentence, just as we do in common parser generation tools. These specifications can be used to systematically process files in directory trees, and the final result depends on the semantic actions associated with each production rule. In this paper we revamped an old idea of using a domain specific language to implement these specifications similar to context free grammars. And introduce some examples of applications that can be built using this approach. }, } @InProceedings{corta2011-oml, author = {Nuno Carvalho and José João Almeida and Alberto Simões}, title = {Weaving {OML} in a General Purpose Programming Language}, booktitle = {INForum'11 --- Simpósio de Informática (CoRTA2011 track)}, editor = {Raul Barbosa and Luis Caires}, publisher = {Dep. de Eng.

They are not, in any way, optimized for a specific set of problems. In contrast, Domain Specific Languages (DSL) are used to solve specific problems in a well defined domain. DSL are optimized to a particular set of problems, but they lack support for a wide range of operations that are required when dealing with real world problems. So, in a perfect world, we would like to implement applications using a general purpose programming language, but use a set of different DSL to handle specific domains' tasks. In this paper we describe a DSL named Ontology Manipulation Language (OML), designed to describe operations over with ontologies. Programs can be written using only the OML syntax and be executed independently. OML syntax was designed to deal with ontologies and the language itself is optimized to perform these tasks, which means that other relatively simpler tasks can not be easily done. To overcome this challenge a mechanism was developed so that you can weave small snippets of OML code inside Perl programs, meaning we have the power of OML to manipulate ontologies and, at the same time, all the paraphernalia of modules that Perl offers to handle everything else. }, } @inproceedings{wims2011, author = {Brett Drury and J.J.

This situation is even more common in web development environments or Service Oriented Architectures (SOA), where data flows from one service to another, being consumed and produced by an heterogeneous set of applications, which sole requirement is to understand XML. This workflow of data represented in XML implies some tasks that applications have to perform if they are required to consume or produce information: the task of parsing an XML document, giving specific semantics to the information parsed, and the task of producing an XML document. Our main goal is to create object definitions that can analyze an XML document and automatically create an object definition that can be used abstractly by the application. These objects are able to parse the XML document and gather all the data required to mimic all the information present in the document. This paper introduces xml2pm, a simple tool that can inspect the structure of an XML document and create an object definition (a Perl module) that stores the same information present in the orinial document, but as a runtime object.

Mgbeg is a simple attributed grammar used to describe the set of valid exercise (and randomly generate one of them). Each exercise typically contains several attributes calculated during the generation steps: namely, one or more formal specification of the language (context free grammar); the exercise statement; other information such as examples, common mistakes, validation data, to be used in the construction of the exercise statement, solution, and assessment steps. Complementary the toolkit provides a grammar module, with functionality for grammar comparison, sentence generation and recognition; a template engine (to help in textual attributes calculation). }, } %%========================= 2018 @incollection{Martins2018a, author = {Ricardo Martins and J.João Almeida and Pedro Rangel Henriques and Paulo Novais}, title = {Increasing authorship identification through emotional analysis}, booktitle = {Trends and Advances in Information Systems and Technologies, WorldCist2018}, offeditor = {Álvaro Rocha and Hojjat Adeli and Luís Paulo Reis and Sandra Costanzo}, series = {Advances in Intelligent Systems and Computing}, publisher = {Springer International Publishing}, year = 2018, volume = 745, pages = {763-772}, edition = 1, month = {March}, doi = {https://doi.org/10.1007/978-3-319-77703-0_76}, isbn = {978-3-319-77702-3} } @inproceedings{DBLP:conf/ideal/MarcondesAN18, author = {Francisco S.

To every context-free grammar there corresponds a system of formal equations. Formally applying the iteration method to this system we obtain the grammar axiom in the form of a formal power series composed of the words generated by the grammar "multiplied" by the respective ambiguities. We define a transform that attributes a matrix meaning to the system of formal equations and to formal power series: terminal symbols are substituted by matrices and formal sum and product are substituted by the matrix ones. In order to effectively compute the sum of a matrix series we numerically solve the system of matrix equations. We prove distinguishability theorems showing that if two formal power series generated by cycle-free context-free grammars are different, then there exists a matrix substitution such that the sums of the respective matrix series are different. Based on this result, we suggest a procedure that can resolve the problem of equivalence of cycle-free context-free grammars in many practical cases. The results obtained in this paper form a theoretical basis for algorithms oriented to automatic assessment of students' answers in computer science. We present the respective algorithms. Then we compare our approach with a simple heuristic method based on CYK algorithm and discuss the limitations of our method. } } @inproceedings{Almeida2019, author={Almeida, J.J. and Mendes, R.C.}, title={Hunting ancestors: A unified approach for discovering genealogical information}, journal={OpenAccess Series in Informatics}, year={2019}, volume={74}, doi={10.4230/OASIcs.SLATE.2019.22}, art_number={22}, url={https://www.scopus.com/inward/record.uri?eid=2-s2.0-85071097688&doi=10.4230%2fOASIcs.SLATE.2019.22&partnerID=40&md5=8e2f42806d411bdfa553dcfa27be17a9}, abstract={This paper presents an unified approach for discovering genealogical information.

This paper provides a description of LeXmart, the framework that supports the digital development of the Portuguese Academy of Sciences Dictionary. LeXmart is a smart tool framework to support lexicographers' work that offers different types of tools, ranging from a structural editor to a set of validation tools. Given that the dictionary is stored in eXist-DB, LeXmart is developed on top of its ecosystem, using W3C standard languages, and offering default functionalities offered by eXist-DB, namely a RESTful API. © 2019 Lexical Computing CZ s.r.o..

Often, this writing style can identify the author. One of the most famous examples comes from 1914 in Portuguese literature. With Fernando Pessoa and his heteronyms Alberto Caeiro, Álvaro de Campos, and Ricardo Reis, who had completely different writing styles, led people to believe that they were different individuals. Currently, the discussion of authorship identification is more relevant because of the considerable amount of widespread fake news in social media, in which it is hard to identify who authored a text and even a simple quote can impact the public image of an author, especially if these texts or quotes are from politicians. This paper presents a process to analyse the emotion contained in social media messages such as Facebook to identify the author's emotional profile and use it to improve the ability to predict the author of the message. Using preprocessing techniques, lexicon-based approaches, and machine learning, we achieved an authorship identification improvement of approximately 5% in the whole dataset and more than 50% in specific authors when considering the emotional profile on the writing style, thus increasing the ability to identify the author of a text by considering only the author's emotional profile, previously detected from prior texts. © 2019 John Wiley & Sons, Ltd.}, document_type={Article}, source={Scopus}, } @inproceedings{Martins2019276, author={Martins, R. and Almeida, J.J. and Henriques, P. and Novais, P.}, title={Domain identification through sentiment analysis}, journal={Advances in Intelligent Systems and Computing}, year={2019}, volume={800}, pages={276-283}, doi={10.1007/978-3-319-94649-8_33}, url={https://www.scopus.com/inward/record.uri?eid=2-s2.0-85049987273&doi=10.1007%2f978-3-319-94649-8_33&partnerID=40&md5=3fe3521d746330d391ee8ec0dd7bd4e9}, abstract={When dealing with chatbots, domain identification is an important feature to adapt the interactions between user and computer in order to increase the reliability of the communication and, consequently, the audience and decrease its rejection avoiding misunderstandings. In order to adapt to different domains, the writing style will be different for the same author. For example, the same person in the role of a student writes to his professor in a different style than he does for his brother. This article presents a process that uses sentiment analysis to identify the average emotional profile of the communication scenario where the conversation is done.

This means treating music sequences as a first class citizen. It will be possible to save those sequences into variables or play them right away, pass them into functions or apply operators on them (like transposing or repeating the sequence). Furthermore, instead of just allowing static sequences to be generated, we'll integrate a music keyboard system that easily allows the user to bind keys (or other kinds of events) to expressions. Finally, it is important to provide the user with multiple and extensible ways of outputing their music, such as synthesizing it into a file or directly into the speakers, or writing a MIDI or music sheet file. We'll structure this paper first with an analysis of the problem and its particular requirements. Then we will discuss the solution we developed to meet those requirements. Finally we'll analyze the result and discuss possible alternative routes we could've taken. © 2020 Schloss Dagstuhl- Leibniz-Zentrum fur Informatik GmbH, Dagstuhl Publishing.

That need requires a formalism to describe properly such behaviors. As the gaming industry has been growing, many approaches were proposed. First, finite state machines were used and evolved to hierarchical state machines. As that formalism was not enough, a more powerful concept appeared. Instead of using states for describing behaviors, people started to use tasks. This concept was incorporated in behavior trees. This paper focuses in the specification and processing of Behavior Trees. A DSL designed for that purpose will be introduced. It will also be discussed a generator that produces LATEX diagrams to document the trees, and a Python module to implement the behavior described. Additionally, a simulator will be presented. These achievements will be illustrated using a concrete game as a case study. © 2020 Schloss Dagstuhl- Leibniz-Zentrum fur Informatik GmbH, Dagstuhl Publishing.

This paper shows that it is possible to generate human likable usernames through heuristics guided by structural onomastics. The objective then is to conceive heuristics as such and check its availability in Twitter in order to verify if is it possible to generate a sufficiently big and available username data-set that is able to justify the transitions from unpleasant to a pleasant username suggestion. This paper finds that it is possible to generate 8281 handles on average through the proposed heuristics and their permutations, therefore, the number of various possibilities is comfortable.

It was then realized that there is not common to use chatbots with this "virtuous" purpose. Therefore, after two surveys and a meta-analysis, the topic had to be withdrawn since there were no survey results to discuss besides the absence of results. The survey result raised then a need to realize how chatbots are being currently used, designed and their primary sources. The result was once again confusing since, on the sample: (1) no significant concentration of usage could be found; (2) no widely adopted design strategies were identified, and (3) no significant crosscutting references to be considered as primary sources. Certainly, this can be due to a biased sample but may also be a symptom of a methodological issue on the chatbot researches. If the second possibility is proved to be right it means that chatbot research is still on a pre-paradigm stage according to Kuhn¿s conception. For this paper, there were performed 4 surveys with a total sample of 50 papers mostly from the last 3 years. © Springer Nature Switzerland AG 2020.}, document_type={Conference Paper}, source={Scopus}, } @ARTICLE{Marcondes2020170, author={Marcondes, F.S. and Almeida, J.J. and Durães, D. and Novais, P.}, title={Fact-Check spreading behavior in twitter: A qualitative profile for false-claim news}, journal={Advances in Intelligent Systems and Computing}, year={2020}, volume={1160 AISC}, pages={170-180}, doi={10.1007/978-3-030-45691-7_16}, url={https://www.scopus.com/inward/record.uri?eid=2-s2.0-85086245198&doi=10.1007%2f978-3-030-45691-7_16&partnerID=40&md5=6547f11464462d6bfdb1505e6142b733}, abstract={Fact-check spread is usually performed by a plain tweet with just the link.
