Users expect search to be simple: They enter a few terms and expect perfectly-organized, relevant results instantly. But behind this simple user experience, complex machinery is at work. Whether using Elasticsearch, Solr, or another search technology, the solution is never one size fits all. Returning the right search results requires conveying domain knowledge and business rules in the search engine's data structures, text analytics, and results ranking capabilities. Relevant Search demystifies relevance work. Using Elasticsearch, it tells how to return engaging search results to users, helping readers understand and leverage the internals of Lucene-based search engines. The book walks through several real-world problems using a cohesive philosophy that combines text analysis, query building, and score shaping to express business ranking rules to the search engine. It outlines how to guide the engineering process by monitoring search user behavior and shifting the enterprise to a search-first culture focused on humans, not computers. It also shows how the search engine provides a deeply pluggable platform for integrating search ranking with machine learning, ontologies, personalization, domain-specific expertise, and other enriching sources. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.

Provides comprehensive coverage of everything that students and practitioners need to know about working in the field of forensic anthropology Forensic anthropology has been plagued by questions of scientific validity and rigor despite its acceptance as a section in the American Academy of Forensic Sciences nearly half a century ago. Critics have viewed it as a laboratory-based applied subfield of biological anthropology, and characterised it as emphasising methodology over theory. This book shows that these views are not only antiquated, but inadequate and inaccurate. Forensic Anthropology: Theoretical Framework and Scientific Basis introduces readers to all of the theoretical and scientific foundations of forensic anthropology — beginning with how it was influenced by the early theoretical approaches of Tyler, Morgan, Spencer and Darwin. It instructs on how modern forensic science relies on an interdisciplinary approach — with research being conducted in the fields of archaeology, physics, geology and other disciplines. This modern approach to theory in forensic anthropology is presented through the introduction and discussion of Foundational, Interpretive and Methodological theories. Sections cover: Bias and Objectivity in Forensic Anthropology Theory and Practice; The Theory and Science Behind Biological Profile and Personal Identification; Scientific Foundation for Interpretations of Antemortem, Perimortem, and Postmortem Processes; and Interdisciplinary Influences, Legal Ramifications and Future Directions. Illustrates important aspects of the theory building process and reflects methods for strengthening the scientific framework of forensic anthropology as a discipline Inspired by the “Application of Theory to Forensic Anthropology” symposium presented at the 67th annual meeting of the American Academy of Forensic Sciences Chapters written by experts in the field who were presenters at the symposium Forensic Anthropology: Theoretical Framework and Scientific Basis is ideal for university courses in anthropological science, forensic science, criminal science and forensic archaeology.

Learn advanced analytical techniques and leverage existing tool kits to make your analytic applications more powerful, precise, and efficient. This book provides the right combination of architecture, design, and implementation information to create analytical systems that go beyond the basics of classification, clustering, and recommendation. Pro Hadoop Data Analytics emphasizes best practices to ensure coherent, efficient development. A complete example system will be developed using standard third-party components that consist of the tool kits, libraries, visualization and reporting code, as well as support glue to provide a working and extensible end-to-end system. The book also highlights the importance of end-to-end, flexible, configurable, high-performance data pipeline systems with analytical components as well as appropriate visualization results. You'll discover the importance of mix-and-match or hybrid systems, using different analytical components in one application. This hybrid approach will be prominent in the examples. What You'll Learn Build big data analytic systems with the Hadoop ecosystem Use libraries, tool kits, and algorithms to make development easier and more effective Apply metrics to measure performance and efficiency of components and systems Connect to standard relational databases, noSQL data sources, and more Follow case studies with example components to create your own systems Who This Book Is For Software engineers, architects, and data scientists with an interest in the design and implementation of big data analytical systems using Hadoop, the Hadoop ecosystem, and other associated technologies.

Elasticsearch ist ein auf Apache Lucene basierender Suchserver, der JSON-Dokumente speichern und durchsuchen kann. Durch den verteilten Aufbau ist die Ablage sehr großer Datenmengen möglich. Neben Volltextinhalten können auch strukturierte Daten verwaltet und mit Aggregationen leicht gruppiert und ausgelesen werden. Dokumente, Suchanfragen und administrative Aufgaben werden in JSON formuliert und per HTTP oder über die Java-API ausgetauscht. Das Buch stellt anhand eines durchgehenden Beispiels die Nutzung von Elasticsearch vor. Nach einem einführenden Kapitel, in dem eine klassische Suchanwendung von Grund auf aufgebaut wird, werden in den anschließenden Kapiteln jeweils unterschiedliche Aspekte genauer beleuchtet. Unter anderem werden die folgenden Themenbereiche angesprochen: • Umgang mit Text • Relevanz in Suchergebnissen • Möglichkeiten der Indizierung • Verteilung der Daten • Datenmodellierung • Aggregationen • Aspekte des Produktivbetriebs • Logdaten in Elasticsearch Der Großteil des Buches ist unabhängig von der Programmiersprache gehalten, es wird jedoch auch auf die Java- und JavaScript-APIs zum Zugriff auf Elasticsearch eingegangen. Der Leser hat nach der Lektüre das notwendige Rüstzeug, um eigene Anwendungen auf Basis von Elasticsearch umzusetzen.
