The complexity of IDS naturally escalates alongside technological advancements, whether they are manually implemented within security infrastructures or elaborated upon in academic literature. However, accessing and comparing these IDS solutions requires sifting through a multitude of hypotheses presented in research papers, which is a laborious and error-prone endeavor. Consequently, many researchers encounter difficulties in replicating results or reanalyzing published IDSs. This challenge primarily arises due to the absence of a standardized process for elucidating IDS methodologies. In response, this paper advocates for a framework aimed at enhancing the reproducibility of IDS outcomes, thereby enabling their seamless reuse across diverse cybersecurity contexts, benefiting both end-users and experts alike. The proposed framework introduces a descriptive language for the precise specification of IDS descriptions. Additionally, a model repository facilitates the sharing and reusability of IDS configurations. Lastly, through a case study, we showcase the effectiveness of our framework in addressing challenges associated with data acquisition and knowledge organization and sharing.

However, this humungous data and its complexity make data exploration and querying challenging even for experts. This led to the demand for easy access to data, even for naive users, all the more evident. Considering this, the database community has tilted toward NoSQL Data stores. While there has been much study on query formulation assistance for NoSQL data stores, many users still want help when specifying complex queries (such as aggregation pipeline queries), which require an in-depth understanding of the data storage architecture of a specific NoSQL data store. To help users perform interactive browsing and navigation in NoSQL data stores (MongoDB), this paper proposes a novel, simple, and user-friendly interface, MTable, that provides users with a presentation-level interactive view. This view compactly presents the query results from multiple embedded documents within a single tabular format compared to MongoDB's find operation, which always returns the main document. A certain cell of the MTable contains clickable hyperlinks for users to interact directly with the data persisted in the document stores. This helps the users to incrementally construct complex queries and navigate the document stores without worrying about the tedious task of writing complex queries. In a user study, participants performed various querying tasks faster with MTable than with the traditional querying mechanism. MTable has received positive subjective feedback as well.</div></div>","PeriodicalId":48552,"journal":{"name":"Journal of Computer Languages","volume":"82 ","pages":"Article 101312"},"PeriodicalIF":1.7,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143101471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conversely, programming experts typically use text-based programming languages like C and Java. Nevertheless, a seamless method for transitioning from a visual- to text-based language has yet to be developed. Therefore, our research project aims to develop a methodology that facilitates this transition by bridging the gap between the two languages and verifying the variations in the biometric information of learners of both languages. In this study, we measured the participants’ heart rate variability (HRV) and evaluated variations in mental stress experienced while learning visual- and text-based languages. The experimental results confirmed that participants proficient in text-based languages experienced lower HRV (indicating higher stress levels) when learning visual-based languages. Conversely, those poorly proficient in text-based languages exhibited higher HRVs (indicating more favorable stress levels) while learning text-based languages. This study successfully observed differences in stress levels while learning both language types using experimental methods. These findings serve as a preliminary step toward clarifying the impact of stress experienced during learning outcomes and identifying the factors that constitute beneficial stress. This study establishes a foundation for an intermediate language that can enhance transitions between the two types of languages.</div></div>","PeriodicalId":48552,"journal":{"name":"Journal of Computer Languages","volume":"82 ","pages":"Article 101311"},"PeriodicalIF":1.7,"publicationDate":"2024-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143101470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The recent inclusion of pattern matching in the Java and Python languages highlights that such a facility is more and more adopted by developers for everyday development. Other main stream programming languages also offer pattern matching capabilities as part of the language (Rust, Scala, Haskell, and OCaml), with different degrees of expressivity in what can be matched. In the meantime, in graphs, pattern matching takes a slightly different turn; it enhances the expressivity of the patterns that can be defined. Smalltalk currently offers little pattern matching capability to find specific objects inside a large graph of objects using a declarative pattern. In Pharo, the closest library to classical pattern matching that exists is the <span>RBParseTreeSearcher</span>, which allows to express specialized patterns over a Pharo Abstract Syntax Tree to find some inner node. The question arises of what features a flexible pattern matching language should have. In this paper, we review the features found in different existing pattern matching languages, both in General Purpose Languages (like Java) and in declarative graph pattern matching languages. We then describe MoTion, a new pattern matching engine for Pharo smalltalk, combining all these features. We discuss some aspects of MoTion’s implementation and illustrate its use with real case examples.</p></div>","PeriodicalId":48552,"journal":{"name":"Journal of Computer Languages","volume":"81 ","pages":"Article 101290"},"PeriodicalIF":1.7,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142129955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the LLVM IRs of the same program can be affected by diverse factors, such as the acquisition source, i.e., compiled from source code or disassembled and lifted from binary code. While the impact of compilation settings on binary code has been explored, the specific differences between LLVM IRs from varied sources remain underexamined. To this end, we pioneer an in-depth empirical study to assess the discrepancies in LLVM IRs derived from different sources. Correspondingly, an extensive dataset containing nearly 98 million LLVM IR instructions distributed in 808,431 functions is curated with respect to these potential IR-influential factors. On this basis, three types of code metrics detailing the syntactic, structural, and semantic aspects of the IR samples are devised and leveraged to assess the divergence of the IRs across different origins. The findings offer insights into how and to what extent the various factors affect the IRs, providing valuable guidance for assembling a training corpus aimed at developing robust LLVM IR-oriented pre-training models, as well as facilitating relevant program analysis studies that operate on the LLVM IRs.</p></div>","PeriodicalId":48552,"journal":{"name":"Journal of Computer Languages","volume":"81 ","pages":"Article 101289"},"PeriodicalIF":1.7,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141937759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
