Better Data Labelling with EMBLEM (and how that Impacts Defect Prediction) [article]

Huy Tu and Zhe Yu and Tim Menzies
2020 arXiv   pre-print
When a new domain is encountered, EMBLEM can learn better ways to label which comments refer to real problems.  ...  For the data sets explored here, EMBLEM better labelling methods significantly improved P_opt20 and G-scores performance in nearly all the projects studied here.  ...  Step 2 Bug-fixing Labelling (Data Labelling): categorize a commit as bug-fixing or not based on the textual content of the commit log.  ...

Identification of microservices from monolithic applications through topic modelling

Miguel Brito, Jácome Cunha, João Saraiva
2021 ACM Symposium on Applied Computing  
This process is slow and, depending on the project's complexity, it may take months or even years to complete.  ...  Microservices emerged as one of the most popular architectural patterns in the recent years given the increased need to scale, grow and flexibilize software projects accompanied by the growth in cloud  ...  That problem was observed initially on projects more complex and bigger in number of components (classes in our case -Java).  ...

Building Corpora of Technical Texts: Approaches and Tools

Petr Sojka, Martin Líska, Michal Ruzicka
2011 Recent Advances in Slavonic Natural Languages Processing  
In particular, there is no widely accepted format to represent and handle math.  ...  We present an approach based on multiple representations of mathematical formulae that has been used for math retrieval, similarity and clustering of mathematical corpus.  ...  Addition of one more keyword Euclid reduces the number of results to only 97 -all of them contain this textual term.  ...

Maintaining dynamic channel profiles on the web

Haggai Roitman, David Carmel, Elad Yom-Tov
2008 Proceedings of the VLDB Endowment  
This work addresses a novel problem of maintaining channel profiles on the Web.  ...  The monitoring scheme is further extended to consider the content that is published on the channels.  ...  Learning a threshold adaptively for each channel can result in even better quality-budget trade-off performance.  ...

Image Exchange: IHE and the Evolution of Image Sharing

David S. Mendelson, Peter R. G. Bak, Elliot Menschik, Eliot Siegel
2008 Radiographics  
The research community is concomitantly developing solutions that solve image exchange issues that are specific to research (eg, the sharing of deidentified data) but that might also be encountered in  ...  Image sharing has evolved from film to transportable media (eg, compact disks) to direct electronic exchange over the Internet.  ...  Acknowledgment: The authors would like to acknowledge and thank Nancy Knight, PhD, Department of Radiology and Nuclear Medicine, University of Maryland School of Medicine, for her assistance in the preparation  ...

MLGO: a Machine Learning Guided Compiler Optimizations Framework [article]

Mircea Trofin
2021 arXiv   pre-print
To the best of our knowledge, this work is the first full integration of ML in a complex compiler pass in a real-world setting. It is available in the main LLVM repository.  ...  The same model, trained on one corpus, generalizes well to a diversity of real-world targets, as well as to the same set of targets after months of active development.  ...  Their evolution (due to training) does not diff well, so the compactness of a binary format is more economical for the project repository. 10 See the buildbot setup script available at https://github.com  ...

Approximate Query Answering for a Heterogeneous XML Document Base [chapter]

Federica Mandreoli, Riccardo Martoglia, Paolo Tiberio
2004 Lecture Notes in Computer Science  
In this paper, we deal with the problem of effective search and query answering in heterogeneous web document bases containing documents in XML format of which the schemas are available.  ...  schemas and to use them in the query processing phase, when a query written on a source schema is automatically rewritten in order to be compatible with the other useful XML documents.  ...  Heterogeneous collections of various types of documents, such as actual text documents or metadata on textual and/or multimedia documents, are more and more widespread on the web.  ...

Adaptive relevance feedback for large-scale image retrieval

Nicolae Suditu, François Fleuret
2015 Multimedia tools and applications  
We have used the ImageNet dataset as it was released in 2010 for most of our evaluations in §4-6.  ...  Then, we sampled uniformly a small collection of 33,000 images (i.e. 3% of the large collection), and another one of 60,000 images (i.e. 6% of the large collection).  ...  Our results give motivation for further investigations on other heuristics or finding more principled ways of trade-off.  ...

Using a multimedia semantic graph for web document visualization and summarization

Antonio M. Rinaldi, Cristiano Russo
2020 Multimedia tools and applications  
In this paper we present a document summarization and visualization technique based on both statistical and semantic analysis of textual and visual contents.  ...  Existing methods for tag-clouds generations are mostly based on text content of documents, others also consider statistical or semantic information to enrich the document summary, while precious information  ...  Moreover, the algorithm includes a trade-off factor which mitigate the problem of favoring more generic concepts in topic identification.  ...
