SPIRE & LA-WEB, 2014

SPIRE 2014 is the 21st edition of the International Symposium on String Processing and Information Retrieval. LA-WEB 2014 is the 9th edition of the Latin American Web Congress. Both conferences will be held in Ouro Preto, Brazil from 20-24 October, 2014. SPIRE will be held in the first three days of the week (20-23 October, 2014), whereas LA-WEB will be held in the last three days of the week (22-24 October, 2014), so that SPIRE and LA-WEB will share joint-sessions on October 22nd, 2014. The conferences will be co-organized by the Department of Computer Science (www.decom.ufop.br) of the Universidade Federal de Ouro Preto (www.ufop.br) and by the Department of Computer Science (www.dcc.ufmg.br) of the Universidade Federal de Minas Gerais (www.ufmg.br).

The scope of the SPIRE series of symposia includes not only fundamental algorithms in string processing and information retrieval, but also SP and IR techniques as applied to areas such as computational biology, DNA sequencing, and Web mining. Given its interdisciplinary nature, SPIRE offers a unique opportunity for researchers from these different areas to meet and network.

LA-WEB aims at providing a venue in Latin America for researchers and technologists from around the world to present, demonstrate and discuss the latest Web developments. LA-WEB is endorsed by the IW3C2 International World Wide Web Conference Committee and the proceedings of LA-WEB 2014 will be published by the Conference Publishing Services (CPS).

About SPIRE

SPIRE 2014 is the 21st edition of the International Symposium on String Processing and Information Retrieval. The event has been held under this title annually since 1998. The four first events concentrated mainly on string processing (SP), and were held in South America under the title South American Workshop on String Processing (WSP) in 1993 (Belo Horizonte, Brazil), 1995 (Valparaiso, Chile), 1996 (Recife, Brazil), and 1997 (Valparaiso, Chile).

WSP was transformed into SPIRE in 1998 (Santa Cruz, Bolivia) when the scope of the event was broadened to include also information retrieval (IR). The change was motivated by the increasing relevance of information retrieval and its close inter-relationship with the general area of string processing. From 1999 to 2007, the venue of SPIRE has been alternating between South / Latin America (odd years) and Europe (even years), with Cancun, Mexico in 1999, A Corua, Spain in 2000, Laguna de San Rafael, Chile in 2001, Lisbon, Portugal in 2002, Manaus, Brazil in 2003, Padova, Italy in 2004, Buenos Aires, Argentina in 2005, Glasgow, UK in 2006, and Santiago, Chile in 2007. This pattern was broken when SPIRE 2008 was held in Melbourne, Australia, but it was probably restarted in 2009 when the venue was Saariselk, Finland. In 2010 SPIRE took place in Los Cabos, Mexico and in 2011 SPIRE was held in Pisa, Italy, in 2012 it was held in Cartagena de Indias, Colombia, and in 2013 it was held in Jerusalem, Israel. Look here for a complete history of the SPIRE series of symposia.

Gonzalo Navarro completed his PhD in Computer Science in 1998 at the University of Chile, where he is currently full professor. His areas of interest include algorithms and data structures, text searching, compression, and metric space searching.He has directed the Millennium Nucleus Center for Web Research, RIBIDI (an Ibero American project funded by CYTED), and a project funded by Yahoo! Research, apart from smaller projects. He has participated in various research projects, such as the Millennium Institute for Cell Dynamics and Biotechnology, an ECOS/CONICYT project (Chile-France cooperation), AMYRI (a CYTED project), and a Fondef project. Currently, he participates of the Millennium Nucleus Information and Coordination in Networks.

Title: Doing SP and IR on Large Repetitive Collections: Keep your friends close, and your enemies closer
Various recent applications where string processing (SP) or information retrieval (IR) tasks are performed are generating huge string collections, which are fortunately highly repetitive in nature: biological sequence collections, versioned document collections, and software repositories are some examples. Many classical SP and IR solutions are overwhelmed by these sizes.
However, the repetitiveness of the collections should be, precisely, the key to successful indexes and data structures to handle them in compressed form. Yet, classical compressed data structures, mostly exploiting statistical compressibility, fail to take advantage of repetitiveness. While grammar and Lempel-Ziv compression exploits repetitiveness, deriving compressed data structures from them is well behind the state of the art of statistically compressed data structures.
In this talk I will review the different forms in which repetitiveness manifests in the typical data structures used for SP and IR, and how this has been exploited in various success stories: inverted indexes, suffix arrays, suffix trees, longest common prefix arrays, XML collections, document arrays, grammar and Lempel-Ziv compressibility. I will also point out several standing challenges that still require new ideas and that may be interesting research topics.

Paolo Boldi obtained his PhD in Computer Science at the University of Milano, where he is currently Associate Professor. His research interests touched many different topics in theoretical and applied computer science, such as: domain theory, non-classical computability theory, distributed computability, anonymous networks, sense of direction, self-stabilizing systems. Recently, his works focused on problems related to the World-Wide Web, a field where his research has also produced software tools used by many people working in the same area.

Title: Monotone Minimal Perfect Hash Functions

Given a set S of n strings, a monotone minimal perfect hash function [SODA 2009] is a data structure that associates to each element of S its rank (among all the elements of S), with respect to the lexicographic ordering.
The function is allowed to return an arbitrary answer when evaluated on an element outside of S.
In the spectrum of perfect hash functions, MMPHFs (Monotone Minimal Perfect Hash Functions) represent a compromise between arbitrary minimal perfect hashing (where _any_ bijective map is allowed) and order-preserving minimal perfect hashing (where a _specific_ bijection is to be represented).
MMPHFs have a wide range of practical applications (dictionaries of search engines, list of URLs of web graphs, etc.) and are becoming an object of interest of many researchers.This talk will discuss the problem of building static MMPHFs both from a theoretical and a practical viewpoint, offering a range of solutions with different tradeoffs between construction time, required space and lookup time.

Berthier Ribeiro-Neto Berthier Ribeiro-Neto got his PhD in Computer Science from UCLA, 1995, under Dick Muntz. In 1996 he joined the CS Department of the Federal University of Minas Gerais, Brazil, where he still teachs part time. In 1999 he co-authored the book "Modern Information Retrieval", with Ricardo Baeza-Yates, which has become a best-seller in the area of Information Retrieval adopted by hundreds of universities around the world. In 2000, he co-founded the search startup "Akwan Information Technologies" acquired by Google in 2005 to become the Engineering Center of Google in Latin America, where he works as Director of Engineering..

Title:Web Search: Challenges and Opportunities

In this talk I provide an introduction to the problem of search, as well as a historical perspective of how search technology evolved over the last 50 years starting with the early work of Information Retrieval pioneers in the 1960s. Following I discuss some of the key challenges faced by modern search engines. Given these challenges, I also explore some open opportunities for research.

His research has been published in leading venues including ICSE, Ubicomp, ICDM, CSCW, RecSys, WSDM, and WWW, received honorable mentions from AAAI ICWSM, and has been featured on La Repubblica, The Independent, New Scientist, Le Monde, and BBC. He spoke at TEDx Barcelona and Falling Walls Berlin, and wrote for BBC. He was Postdoctoral Associate at the Massachusetts Institute of Technology where he worked on social networks in a city context, and his PhD thesis at UC London was nominated for BCS Best British PhD dissertation in Computer Science. During his PhD, he was a Microsoft Research PhD Scholar and MBA Technology Fellow of London Business School, and he also interned at the National Research Council in Barcelona and at National Institute of Informatics in Tokyo. He studied at Politecnico di Torino (Italy), Karlsruhe Institute of Technology (Germany), and University of Illinois (USA).

Title: The Pursuit of Urban Happiness

How can we change architecture to design more for the people and less for the architects? Daniele Quercia presents crowd-based solutions with which urban planners can get valuable information about what kind of urban design is attractive to the people. This leads to GPS systems that show you the "most beautiful" path to your destination and to indicators about the beauty of a city.

Information for participants

SPIRE 2014

SPIRE and LA-WEB 2014 will take place in the historic town of Ouro Preto, Brazil. Ouro Preto is located approximately 100 km from Belo Horizonte, the capital of the state of Minas Gerais in Brazil. Famous for its magnificent well-preserved Portuguese colonial architecture, Ouro Preto was the first city in Brazil to be declared World Cultural and Historical Heritage Site by UNESCO. The 18th- and 19th-century churches decorated with gold and Baroque sculptures make the city a prime tourist destination.

La-Web 2014 Demo Track
October 24th, 2014


Call for Demo Papers:

Starting this year, the Latin American Web Congress (La-Web'2014) will have a demo track in order to provide a venue for presentation of practical work in the field of Web and its related areas.

Demo papers must be in English (4 pages) and formatted in accordance with the instructions provided on the Conference Publishing Services (CPS) (For your submission you can use the standard conference templates). Submissions are single-blinded (not anonymized). Accepted papers for the demo track will be published in the La-Web'2014 proceedings by the CPS and be submitted to the Digital Library.

Demo papers must be submitted exclusively through LA-WEB 2014 demo paper submission Web site. By submitting a paper, its authors commit to having the paper presented at the conference and demonstrating the system during the demo session.

The scope of the La-Web 2014 Demo Track is the same as for the World Wide Web Conference. The instructions on the characteristics of the expected demo paper were taken from the WWW'2014 call for papers (Demo Track ).

The Demo Track allows researchers and practitioners to demonstrate new systems in a dedicated session. Demo submissions must be based on an implemented and tested system that pursues one or more innovative ideas in the interest areas of the conference. Demos from the traditional research community are of course strongly encouraged, but proposals from other activity areas are also welcome. Software (including games or learning platforms) and hardware demos will also be considered, as long as they show innovative use of Web-based techniques.

Each demo submission must make clear which aspects of the system will be demonstrated, and how. They should strive to state the significance of the contribution to Web technology or applications. Demos will be peer-reviewed by members of the Demo Track Program Committee, who will judge the originality, significance, quality, and clarity of each submission.

To better identify the value of demos, as well as to reach out to external audiences, we also encourage authors to submit a pointer to a screencast, using web-accessible platforms such as Vimeo or Youtube. The maximum duration of screencasts is 10 minutes. Running systems demonstrated are also welcome.
