Migration from a Commercial Search Platform (specifically FAST ESP) to Lucene/Solr
Presented by Michael McIntosh, VP, Enterprise Search Technologies, TNR Global
There are many reasons that an IT department with a large scale search installation would want to move from a proprietary platform to Lucene Solr. In the case of FAST Search, the company’s purchase by Microsoft and discontinuation of the Linux platform has created an urgency for FAST users.
This presentation will compare Lucene/Solr to FAST ESP on a feature basis, and as applied to an enterprise search installation. We will further explore how various advanced features of commercial enterprise search platforms can be implemented as added functions for Lucene/Solr. Actual cases will be presented describing how to map the various functions between systems.

Building Google-in-a-box: using Apache SolrCloud and Bigtop to index your big...rhatr
You’ve got your Hadoop cluster, you’ve got your petabytes of unstructured data, you run mapreduce jobs and SQL-on-Hadoop queries. Something is still missing though. After all, we are not expected to enter SQL queries while looking for information on the web. Altavista and Google solved it for us ages ago. Why are we still requiring SQL or Java certification from our enterprise bigdata users? In this talk, we will look into how integration of SolrCloud into Apache Bigtop is now enabling building bigdata indexing solutions and ingest pipelines. We will dive into the details of integrating full-text search into the lifecycle of your bigdata management applications and exposing the power of Google-in-a-box to all enterprise users, not just a chosen few data scientists.
Slide From DataEngConf 2015 event.
LinkedIn is the professional profile of record for our 400M+ members globally, but many people don't realize the full potential of their LinkedIn profile – especially on mobile. Adding blogs, photos and other rich content to your profile on a small screen device can get tedious. That's why LinkedIn created Satori, a Hadoop tool that crawls the web and extracts data to discover members' professional content online. Satori uses machine learning techniques and leverages other open source tools like Nutch and Gobblin in order to help match members with relevant content in order to maximize their professional profile. In this talk, Nikolai Avteniev, Sr. Staff Engineer and Agile Software Developer at LinkedIn, will share his experience in building the product and discuss the challenges and opportunities encountered along the way.
The Search Is Over: Integrating Solr and Hadoop in the Same Cluster to Simpli...lucenerevolution
Presented by M.C. Srivas | MapR. See conference video - http://www.lucidimagination.com/devzone/events/conferences/lucene-revolution-2012
This session addresses the biggest issue facing Big Data – Search, Discovery and Analytics need to be integrated. While creating and maintaining separate SOLR and Hadoop clusters is time consuming, error prone and difficult to keep in synch, most Hadoop installations do not integrate with SOLR within the same cluster. Find out how to easily integrate these capabilities into a single cluster. The session will also touch on some of the technical aspects of Big Data Search including how to; protect against silent index corruption that permeates large distributed clusters, overcome the shard distribution problem by leveraging Hadoop to ensure accurate distributed search results, and provide real-time indexing for distributed search including support for streaming data capture. Srivas will also share relevant experiences from his days at Google where he ran one of the major search infrastructure teams where GFS, BigTable and MapReduce were used extensively.
This talk will give an overview of Apache Nutch, its main components, how it fits with other Apache projects and its latest developments.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).
