The document discusses using JSON and RESTful APIs for database interaction on the web. It covers HTTP methods like GET, PUT, POST, and DELETE for CRUD operations. Various client-side and server-side frameworks that support this approach are also mentioned. Finally, it discusses additional JSON-based standards and techniques for querying, referencing, notifications, and security when using RESTful databases.
The document discusses the advantages of REST over SOAP for web services. REST fits well for stateless services that are accessed through resource URLs and HTTP methods. It is better suited than SOAP for frequent AJAX calls due to its lighter payload and overhead. REST should be used where bandwidth is limited, and can be easily implemented into existing systems. JSON is also discussed as the preferred data exchange format due to its lightness and ease of use compared to XML. The document recommends REST and JSON for scalable, fast web services.
This document discusses the power of open data and how making data available online can enable new applications and discoveries. It provides examples of how open government data allowed for the creation of apps like a gas pump inspection checker. The document also discusses how RESTful principles and APIs have allowed systems like Twitter to be used in new ways not envisioned by their creators by opening their data to developers through standardized interfaces. Overall, the key message is that opening data can fuel innovation and discovery at a relatively low cost.
Done reread detecting phrase-level duplication on the world wide weJames Arnold
The document describes techniques developed by the authors to detect automated generation of web pages through phrase-level duplication. It analyzes two large datasets of web pages collected in 2002 and 2004, finding instances of pages composed largely of repeated popular phrases. The algorithms used identify phrase replication by extracting random phrases from pages and comparing them, allowing detection of sites engaging in similar automated page generation.
The document provides guidelines for designing RESTful APIs including using HTTP verbs for CRUD operations, plural nouns for resource collections, associating resources through nested URLs, parameterizing requests through query strings and headers, supporting pagination, versioning APIs through URI paths and headers, and returning error responses with status codes and messages. Key guidelines include designing resources as nouns, using consistent and intuitive URIs, and making APIs self-descriptive through hypermedia as the engine of application state.

Scraping with Python for Fun and Profit - PyCon India 2010Abhishek Mishra
Tim Berners-Lee - On the Next Web talks about open, linked data. Sweet may the future be, but what if you need the data entangled in the vast web right now?
Mostly inspired from author's work on SpojBackup, this talk familiarizes beginners with the ease and power of web scraping in Python. It would introduce basics of related modules - Mechanize, urllib2, BeautifulSoup, Scrapy, and demonstrate simple examples to get them started with.
1) Web developers build web applications that run on the internet and are accessed through URLs, but these applications can be vulnerable to SQL injection attacks if user input is not sanitized properly.
2) Both web servers and web applications should write log files of requests to help with debugging, performance, and security issues like data breaches.
3) Logging has challenges related to disk space, performance, and reviewing the logs, but reviewing logs can help web developers act as "digital forensics guys" and detect breaches early by searching logs for keywords.

This document provides instructions for creating a simple router in PHP. It begins by explaining the goals of displaying a calendar and handling a birthday form. It then discusses .htaccess files and how they can redirect all requests to an index.php file. The index.php file acts as a router, checking the $_SERVER variable to determine which page has been requested and including the appropriate PHP file. Specific routes are shown for the calendar, birthday, and index pages. Testing the application is recommended to confirm it is routing requests correctly.
An API allows websites and services to make some of their data available to the public for use in applications. The Twitter API allows users to access Twitter data through scripts and programs. This document provides instructions for using existing Python scripts that interface with the Twitter API to search for and retrieve tweets. It also discusses how the Spotify API can be used to access music data like related artists and top tracks of specific artists. Users are encouraged to experiment with different endpoints of the Spotify API to find interesting data for a final project.
In this presentation, I have explained what is a disavow file and how the disavow tool of Google can be used to clear off spammy links from your link portfolio.
AMS, API, RAILS and a developer, a Love StoryJoão Moura
A lot of people have being using Rails to develop both their internal or external API, but building a high quality API can be hard, and performance is a key point to achieve it.
I'll share my stories with APIs, and tell you how Active Model Serializer, component of Rails-API, helped me. AMS have being used across thousands of applications bringing convention over configuration to JSON generation.
This talk will give you a sneak peek of a new version of AMS that we have being working on, it's new cache conventions, and how it's being considered to be shipped by default in new Rails 5.

The Past, Present, and Future of Digital Publishing That Hasn't, Isn't, But M...BookNet Canada
EPUB has been around since 2007; EPUB 3 came out in 2011. We’re told we live in an age of digital disruption, but little has changed in ebooks since before the very first ebookcraft. What’s going on? What might the future of ebooks look like? Should we use EPUB 3.2? Will there ever be an EPUB 4? Are Web Publications real? Part history lesson, part unhinged rant, part futile attempt to predict the future, Dave Cramer will shed light, or at least heat, on the big picture.

Format: Demo/Training
Language: Ruby/Cucumber/Watir/PageObject
Audience Participation: Mandatory!
If you work in the field of testing/QA then it is likely that you have encountered test automation in one form or another. Maybe you have embraced it and have gained expertise. Or maybe you’ve avoided it because you’re hoping it’s a fad that will fade away. I’m guessing most of you would like to learn it but don’t know where to start.
My goal is simple: to demystify the subject by taking a novice tester with no coding experience through the process of writing a simple automated test using the Page Object framework in Ruby/Cucumber. I will take a volunteer from the audience and transform that person from an ordinary QA professional (or whatever their occupation) into an automation engineer in one short hour.
Don’t be afraid; the code will not bite. Much.

The document discusses the growth of APIs and argues that APIs need to adopt HATEOAS (Hypermedia as the Engine of Application State) principles in order to become browsable and drive mass adoption. It outlines how relationships between resources are important for enabling browsability, versionless APIs, and network effects. The author describes their company Elastic Path's past failed API efforts and its Cortex API engine, which was built to help implement HATEOAS principles and address issues they encountered with other frameworks.
The document provides instructions for uploading web pages to the internet using free server space and an FTP program. It explains that free server space can be provided by an internet provider or companies like Angelfire. An FTP program like FileZilla is needed to transfer files from a local computer to the server. The document gives step-by-step instructions for connecting to the server using the FTP program, navigating to the local and remote sites, selecting files to upload, and making one page the index page so it is the default home page for the site. It also recommends eventually purchasing a custom domain name.
This document provides an outline for a presentation on a given topic. It includes sections for an introduction, defining the topic, stating a thesis, presenting two opposing viewpoints with supporting evidence, discussing religious aspects, concluding statements, and closing remarks for questions. The outline suggests including an anecdote, definition, graphs, and summarizing sources to engage the audience while verbally expanding on the main points.
This document provides an introduction to game theory. It discusses what game theory is, its essential features, and some key concepts in game theory including Nash equilibrium, backward induction, extensive form games, normal form games, mixed strategies, coordination games, zero-sum games, the prisoner's dilemma, chicken games, and repeated games. It also provides examples of applying game theory concepts to real-world situations such as the rivalry between Airbus and Boeing.
Game theory is a branch of applied mathematics that analyzes strategic interactions between rational decision-makers. It was developed by John von Neumann and Oskar Morgenstern in the 1940s. Game theory has applications in economics, military strategy, politics, and other domains involving conflict and cooperation between intelligent decision-makers. The document defines key concepts in game theory like Nash equilibrium, zero-sum games, prisoner's dilemma, and mixed strategies. It also discusses assumptions of game theory and provides examples of classic game theory models.
This document discusses ethics and business ethics. It defines ethics as the study of good and bad behavior and morality. Business ethics refers to applying ethical standards to business practices and decisions. The document outlines several approaches to ethical standards like utilitarianism and virtue ethics. It also discusses ethical dilemmas that can arise in business when there are conflicts between ethical decisions and business interests. Overall, the document provides an overview of ethics and emphasizes the importance of following ethical practices in business.
This presentation is an attempt to introduce Game Theory in one session. It's suitable for undergraduates. In practice, it's best used as a taster since only a portion of the material can be covered in an hour - topics can be chosen according to the interests of the class.
The main reference source used was 'Games, Theory and Applications' by L.C.Thomas. Further notes available at: http://bit.ly/nW6ULD
This document provides an overview of game theory concepts taught in a university course. It defines game theory as the mathematics of human interactions and decision making. Key concepts discussed include Nash equilibrium, where each player adopts the optimal strategy given other players' strategies. Examples of applications are given in fields like economics, politics and biology. Different types of games and solutions concepts like mixed strategies are also introduced.
This document summarizes Christian Heilmann's presentation about three Yahoo products that can help developers: Placemaker for adding geographical context to content, YQL for mixing data from different sources, and YUI for building layouts and widgets that work across browsers. Placemaker uses natural language processing to associate text with locations. YQL allows querying data from various web sources and combining it through a simple SQL-like syntax. YUI is a development framework that includes CSS grids, common widgets, and tools to help build sites that render consistently on different browsers and devices.
The document provides an overview of the Semantic Web and linked data. It defines the Semantic Web as publishing structured data on the web in a format that computers can understand, rather than just documents. Linked data follows principles like using URIs to identify things and linking data across sources to integrate information. Query languages like SPARQL can then be used to search across linked data. Examples show how data can be published as RDF and linked to create a global database. Applications that consume and combine linked data from multiple sources are discussed.
This document describes a web agent designed to help users discover web resources like HTML documents and PostScript files. The agent uses a web-wandering robot that crawls the web in breadth-first order to index HTML documents and extract PostScript file URLs. It stores the title, URL, and first 50 words of indexed HTML documents. For PostScript URLs, it indexes the URL along with 100 words of text containing the link. The agent allows users to search these indexes to find relevant resources.
Research on Internet Search Engine during my masters studies on 1995. Conducted research on Text Processing Algorithm and Database. Using PERL5 in Sun Solaris platform an Internet Search Engine (Robot) was designed and implemented during 1995 to make digital library of the Web resources.

This document provides an introduction to the Semantic Web and RDF (Resource Description Framework). It discusses how the Semantic Web aims to extend the current web by giving data well-defined meaning to enable computers and people to better work together. It introduces RDF as a standard for representing information in the Semantic Web and provides examples of how RDF can be used to represent different types of data, such as relational data and evolving data scenarios.
Alternative ways of developing web sites using EPiServer CMS. An introduction to three open source frameworks that allow us to better tackle complexity, have a more enjoyable development experience and deliver better, well tested sites using EPiServer CMS.
This document provides an introduction to linked data and the semantic web. It discusses how the current web contains documents that are difficult for computers to understand, but linked data publishes structured data on the web using common standards like RDF and URIs. This allows data to be interlinked and queried using SPARQL. Publishing data as linked data makes the web appear as one huge global database. There are now many incentives for organizations to publish their data as linked data, as it enables data sharing and integration in addition to potential benefits like semantic search engine optimization. Linked data is a growing trend with many large organizations and governments now publishing data.
Nt1310 Final Exam Questions And AnswersLisa Williams
This document discusses current and future developments in open source software and information and communications technology (ICT). It first defines open source operating systems and provides examples like Linux and Kubuntu. It then defines open source application software and examples like Mozilla Firefox. It concludes by discussing recent hardware developments like Canon printers released in 2011 and 2012 that allow printing, scanning, copying and faxing over wireless connections.
Community, metadata, ranking and websites that grow over time are attributes of Web2.0. What else? Come to the University of Cheikh Anta Diop Campus, ESP. Then, stroll over to the first meeting of SeneJUG and find out. Mike Levin will tell you all about Web2.0 and even show you some snippets in Java. We’ll talk about mashups, semantics, custom RSS feeds based on smart filters, tags and tag clouds, and a glimpse into the future. We’ll check out a fantastically popular Web2.0 website and do a feature walkthrough so you’ll be clear about the Web2.0 features. You’ll walk away with some facts and a few ideas that might inspire you to write your own Web2.0 website.
This document discusses using web services in JavaScript. It summarizes how Yahoo Query Language (YQL) can be used to simplify accessing and combining multiple web APIs. YQL allows web services to be accessed like databases, avoiding complex asynchronous code. Examples show how to get distance between places, translate tweets, and find keywords for a location. Caching responses locally for faster loading is also covered. Developers can expose their own APIs through YQL by writing executable tables. The document encourages reuse of web data and building on existing services through YQL.
Synchronous Reads, Asynchronous Writes refers to an architectural approach where data reads are performed synchronously through services, while data writes are performed asynchronously through a messaging system. This allows for decoupling of services, horizontal scaling of reads and writes, and loose coupling between systems. The key aspects are performing JSON RESTful reads through services like Sinatra, and pushing writes to a messaging system like RabbitMQ with routing keys to trigger downstream processing. This approach can help solve issues with monolithic Rails applications that do not scale effectively.
This document provides an overview of a web crawler project implemented in Java. It includes sections on the theoretical background of web crawlers, using a DOM parser to parse XML files, software analysis including requirements and design, and software testing. The project involves building a web crawler that takes a fully built XML website and recursively visits all pages, saving links in a hash table and then printing them. It parses XML files into a DOM representation and uses classes like Main and WebCrawler to implement the crawling functionality.
Treading the cowpaths of the information superhighway.Christian Heilmann
My talk at ignite London explaining the benefits of allowing people to use the infrastructure they are used to and bring their content onto the web instead of forcing them into a web interface they don't like using.
The document discusses the evolution of the World Wide Web from Web 1.0 to the current Web 2.0 and provides definitions and perspectives on what Web 3.0 may entail. Key aspects of Web 3.0 discussed include it being called the "Semantic Web" or "Intelligent Web" which will allow computers to better understand and process the meaning of information on the web through technologies like RDF, RDFS, OWL and SPARQL.
The document discusses RESTful web services and different types of web service architectures. It defines web services as a method of communication between electronic devices over a network. RESTful web services use HTTP methods like GET, POST, PUT, DELETE to convey method information and URIs to specify scoping information. Other architectures may use XML bodies or SOAP headers instead of HTTP methods. Web services can be classified as RESTful, RPC-style, or a REST-RPC hybrid based on how they handle method and scoping information.
We are obsessed with coding and creating automated workflows and optimisations. And yet our final products aren't making it easy for people to use them. Somewhere, we lost empathy for our end users and other developers. Maybe it is time to change that. Here are some ideas.
This document discusses ways to improve how web developers learn best practices through browser and tooling improvements. It suggests that linting and inline insights directly in code editors could help prevent mistakes by flagging issues early. A tool called webhint is highlighted that provides one-stop checking and explanations of hints related to performance, accessibility, security and more. The document advocates for customizing hints based on a project's specific needs and environment. Overall, it argues for accelerated learning through context-sensitive, customizable best practices integrated into development workflows.
This document discusses privilege in the context of social media and the internet. It acknowledges privileges like internet access, the ability to communicate, and supportive online communities. It warns that machine learning and algorithms risk creating echo chambers and guided messaging if they are not kept in check by human curation. The document advocates taking back the web for decent, thinking and loving humans and using privileges to help others gain access to learning, communication, and communities.
This document discusses artificial intelligence and how it can help humans. It covers that AI is not new, having originated in the 1950s, and is now more advanced due to increased computing power. It also discusses how AI utilizes pattern recognition and machine learning. The document then covers several applications of AI including computer vision, natural language processing, sentiment analysis, speech recognition/conversion and moderation. It notes both the benefits of AI in automating tasks and preventing errors, as well as the responsibilities of ensuring transparency and allowing people to opt-in to algorithms.
Killing the golden calf of coding - We are Developers keynoteChristian Heilmann
The document discusses concerns about the perception and realities of coding careers. It expresses worry that coding is seen solely as a way to get a job rather than as a means of problem-solving. While coding can provide fulfilling work, the document cautions that the need for coders may decrease with automation and that the role may evolve from coding to engineering. It suggests a future where machines assist with repetitive coding tasks and people focus on delivering maintainable, secure products with attention to privacy and user experience.
PWA are a hot topic and it is important to understand that they are a different approach to apps than the traditional way of packaging something and letting the user install it. In this keynote you'll see some of the differences.
This document discusses privilege in technology and perceptions of technology workers. It acknowledges the privileges that tech workers enjoy, such as access to resources and high demand in the job market. However, it also notes problems like peer pressure, lack of work-life balance, and imposter syndrome. Both tech workers and the public have skewed perceptions of each other - tech workers feel others do not appreciate or understand their work, while the public sees tech workers as antisocial or caring only about profit. The document encourages taking small steps to improve the situation, such as being kind to oneself, considering others, sharing knowledge, and focusing on quality over quantity of work.
The document provides five ways for JavaScript developers to be happier:
1) Concentrate on the present and focus on creating rather than worrying about the past or future.
2) Limit distractions by streamlining your development environment and using an editor like VS Code that consolidates features.
3) Make mistakes less likely by using linters to catch errors as you code.
4) Get to know your tools better like debuggers to avoid console.log and gain insights to build better solutions.
5) Give back to others in the community by being helpful rather than causing drama.
The document discusses progressive web apps (PWAs) and provides suggestions for improving them. It notes that while PWAs aim to have engaging, fast, integrated, and reliable experiences like native apps, they still have room for improvement in areas like speed, integration, and reliability. It emphasizes that PWAs should adhere to web best practices and provide actually useful experiences rather than just focusing on technical features. The document encourages helping the PWA effort by providing feedback, using and contributing to tools, keeping messaging up-to-date, and promoting high-quality examples.
Chris Heilmann gave a talk at BTConf in Munich in January 2018 about machine learning, automation worries, and coding. He discussed how coding used to refer to creative programming within technical limitations but now often refers to programming for work. He addressed common worries about new technologies and dependencies, and argued that abstractions are not inherently bad and help more people build products together through consensus. The talk focused on using tools to be more productive and enabling rather than seeing them as dangers, and creating solutions for users rather than fighting old approaches.
The document provides advice and encouragement for someone starting out with JavaScript development. It discusses how JavaScript can be used in many environments like browsers, apps, and servers. It recommends resources like MDN and tools like linting to help avoid mistakes. It emphasizes that this is an exciting time for JavaScript and advises setting priorities and standards, being involved in the community, and bringing new voices and perspectives.
Keynote at halfstackconf 2017 discussing the falsehood of the idea that in order to survive the automation evolution everybody needs to learn how to code. Machines can code, too.
Progressive Web Apps - Covering the best of both worlds - DevReachChristian Heilmann
Progressive Web Apps (PWAs) can provide app-like experiences through the web by making web content fast, reliable and engaging. While PWAs may not be necessary for all projects, they can help clean up and speed up current web-based projects. PWAs leverage new web capabilities like service workers to work offline, load fast, and improve the user experience without having to meet all the requirements of native apps.
Progressive Web Apps - Covering the best of both worldsChristian Heilmann
This document discusses progressive web applications (PWAs) and their advantages over traditional native mobile applications. PWAs use modern web capabilities like Service Workers to deliver native-like experiences to users. Some key benefits of PWAs include their ability to work across platforms, have smaller file sizes for faster loading, support offline use, and provide simple update mechanisms compared to native apps. While PWAs do not have full access to device capabilities like native apps, they allow delivering app-like web content to users in a more accessible and reliable manner than traditional web pages.
Progressive Web Apps - Bringing the web front and center Christian Heilmann
This document discusses progressive web apps (PWAs). It notes that PWAs aim to make web apps feel like native mobile apps by being discoverable, installable, linkable, safe, responsive and progressive. The document outlines some key characteristics of PWAs, including that they need to be served from secure origins and have app manifests. It also discusses some common misconceptions around PWAs and notes that as PWAs improve, they will continue to blur the line between web apps and native mobile apps.
This document discusses the differences between CSS and JavaScript and when each is most appropriate to use. It argues that CSS is often underestimated in favor of JavaScript solutions. CSS has advanced significantly with features like calc(), media queries, animations/transitions, flexbox, grid, variables and more. These powerful features allow many tasks to be accomplished with CSS alone without needing JavaScript. The document encourages embracing the "squishiness" of the web and considering CSS more when building interfaces.
This document contains the transcript of a presentation by Chris Heilmann on web development. Some of the key points discussed include:
- The benefits of progressive enhancement and using HTML, CSS, and JavaScript together to build robust and accessible websites.
- How limitations in early design can foster creativity.
- The importance of error handling and defensive coding practices.
- Embracing new technologies like Service Workers and Manifests to build Progressive Web Apps.
- Rethinking the idea that JavaScript is unreliable and should not be depended on, as modern browsers have made it a capable tool.
The Soul in The Machine - Developing for Humans (FrankenJS edition)Christian Heilmann
The document discusses how machines and software can help humans by doing tasks like preventing mistakes, performing repetitive tasks, filling information gaps, remembering and categorizing information, improving understanding, enabling new communication methods, and providing protection. It describes how advances in AI, APIs, cloud services, and data processing have made it possible to build useful and helpful interfaces. The conclusion encourages developers to use these capabilities to create simple, human-centric interfaces that benefit users.
Lucid Dreaming: Understanding the Risks and Benefits
The ability to control one's dreams or for the dreamer to be aware that he or she is dreaming. This process, called lucid dreaming, has some potential risks as well as many fascinating benefits. However, many people are hesitant to try it initially for fear of the potential dangers. This article aims to clarify these concerns by exploring both the risks and benefits of lucid dreaming.
The Benefits of Lucid Dreaming
Lucid dreaming allows a person to take control of their dream world, helping them overcome their fears and eliminate nightmares. This technique is particularly useful for mental health. By taking control of their dreams, individuals can face challenging scenarios in a controlled environment, which can help reduce anxiety and increase self-confidence.
Addressing Common Concerns
Physical Harm in Dreams Lucid dreaming is fundamentally safe. In a lucid dream, everything is a creation of your mind. Therefore, nothing in the dream can physically harm you. Despite the vividness and realness of the dream experience, it remains entirely within your mental landscape, posing no physical danger.
Mental Health Risks Concerns about developing PTSD or other mental illnesses from lucid dreaming are unfounded. As soon as you wake up, it's clear that the events experienced in the dream were not real. On the contrary, lucid dreaming is often seen as a therapeutic tool for conditions like PTSD, as it allows individuals to reframe and manage their thoughts.
Potential Risks of Lucid Dreaming
While generally safe, lucid dreaming does come with a few risks as well:
Mixing Dream Memories with Reality Long-term lucid dreamers might occasionally confuse dream memories with real ones, creating false memories. This issue is rare and preventable by maintaining a dream journal and avoiding lucid dreaming about real-life people or places too frequently.
Escapism Using lucid dreaming to escape reality can be problematic if it interferes with your daily life. While it is sometimes beneficial to escape and relieve the stress of reality, relying on lucid dreaming for happiness can hinder personal growth and productivity.
Feeling Tired After Lucid Dreaming Some people report feeling tired after lucid dreaming. This tiredness is not due to the dreams themselves but often results from not getting enough sleep or using techniques that disrupt sleep patterns. Taking breaks and ensuring adequate sleep can prevent this.
Mental Exhaustion Lucid dreaming can be mentally taxing if practiced excessively without breaks. It’s important to balance lucid dreaming with regular sleep to avoid mental fatigue.
Lucid dreaming is safe and beneficial if done with caution. It has many benefits, such as overcoming fear and improving mental health, and minimal risks. There are many resources and tutorials available for those interested in trying it.

Chandra Dev: Unveiling the Mystery of the Moon GodExotic India
Shining brightly in the sky, some days more than others, the Moon in popular culture is a symbol of love, romance, and beauty. The ancient Hindu texts, however, mention the Moon as an intriguing and powerful being, worshiped by sages as Chandra.
Astronism, Cosmism and Cosmodeism: the space religions espousing the doctrine...Cometan
This lecture created by Brandon Taylorian (aka Cometan) specially for the CESNUR Conference held Bordeaux in June 2024 provides a brief introduction to the legacy of religious and philosophical thought that Astronism emerges from, namely the discourse on transcension started assuredly by the Cosmists in Russia in the mid-to-late nineteenth century and then carried on and developed by Mordecai Nessyahu in Cosmodeism in the twentieth century. Cometan also then provides some detail on his story in founding Astronism in the early twenty-first century from 2013 along with details on the central Astronist doctrine of transcension. Finally, the lecture concludes with some contributions made by space religions and space philosophy and their influences on various cultural facets in art, literature and film.

1. Introducing Placemaker
Christian Heilmann | http://wait-till-i.com | http://twitter.com/codepo8
YDN Tuesday at Skills Matter, London, UK, July 2009
2. Spatial
Fanboy
Hello, I am Chris. Hacker by passion. When I went to the first WhereCamp about two years ago I
thought nobody can out-geek me. I was wrong. Geolocation and Geocoding is quite some hard-core
branch of geekery. So let me tell you about a nice little product that makes things easy for you.
3. Placemaker
http://developer.yahoo.com/geo/placemaker/
This is Yahoo Placemaker and it is an API. You give it a URL to get data from or a text to extract
geographical information from. Here are the docs. Now go forth and build cool stuff.
5. A web of information
The web is full of information. Which is cool. The problem is that we accumulated and still
accumulate more and more information without giving it proper structure.
6. Searching & Finding
Search engines help us find stuff. However, as being found means making money the first search
results are not necessarily the best - only the ones that have been promoted the best way.
7. Analysing & deciding
http://www.flickr.com/photos/briannasdksdk/1698458575/
Analyzing all the data of the web is a massive job. And computers are stupid. Computers are
decision engines that would be thoroughly stumped when asked "do I look fat in this dress" as they
forget the underlying dangers in answering this question in one way or another.
8. Human additives
This is why we need humans. By enriching our content with structured, easier to parse data we make
it easier for machines to harvest only the necessary parts of our documents. In the past that was
keywords, now we use microformats and tagging. The latter is very useful as it can be
crowdsourced. People tagging my photos on flickr or my site on del.icio.us make it easier for them
to find them later on and give me an idea what keywords I hadn't thought of.
9. Mobility
http://vimeo.com/2638558
This is all fine and good, but the real change we see in behaviour of web users is that we become
more and more mobile. This also means that people can locate themselves on the planet and expect
information from their physical surroundings. In other words, for our content to be found we need
to have geographical information in there that defines the locality of the text, not only what it talks
about.
10. Hidden goodies
Texts on the web have all kind of great information in them - if we find a tool that finds and marks
them for us.
11. Free Text Places
URL References
Placemaker is a service that converts text or URLs in places and references.
13. Calling Placemaker
http://wherein.yahooapis.com/v1/
document
documentContent=First+we+take
+Manhattan+and+then+we+take
+Berlin.
documentType=text/plain
appid=my_appid
To find the geographical information in this text simply send it to Placemaker via POST.
14. Parameters
appid - nothing happens without it!
inputLanguage documentURL
fr-CA,de-DE... url to analyze
outputType documentType
xml or RSS MIME type of doc
documentContent autoDisambiguate
text to analyse remove duplicates
documentTitle focusWoeid
additional title filter around a woeid
Placemaker takes several parameters that allows you to get the data you want.
15. First we take
Manhattan, and then
we take Berlin.
Let’s take this classic sentence and run it through Placemaker.
16. First we take
Manhattan, and then
we take Berlin.
This is the result we get back from Placemaker when we send the text through it.
20. Places
First up is a list of places the API found in the text. These are PlaceDetails elements with a nested
place element:
21. References
This is cool, but it doesn't tell us where this information came from. For this there is a referenceList
element with an array of references. In order to find out where the text Placemaker found as a
match is located in the document, you either get start and end for text content of the XPATH for
structured content (XML/RSS).
23. 50,000 bytes
Placemaker text requests are limited to 50,000 bytes which is a lot but may not be enough,
especially when the data you try to analyse is not your own.
24. The broken web
The web is full of terribly badly organized content. Using the documentUrl property Placemaker
happily loads the information but can choke on some things content providers sadly enough do -
like encoding documents in UTF-8 and then using non-UTF-8 characters.
25. POST vs. GET
Placemaker does not allow for GET requests, even if they were short enough to go through without
problems.
26. !JSON
Placemaker has no JSON output at the moment, which means you cannot use results in JavaScript
without writing an own converter.
27. Places vs. References
There is a list of Places and a list of References, but they are not directly connected. Furthermore
References have a parent element whereas places don’t.
29. YQL to fix the web.
YQL has an HTML parser which doesn’t mind bad encodings and runs results through HTML tidy to
clean it up.
30.
31.
32.
33. Connecting places
and references
If we want to use places and bring them back into the original text we need to go through a small
conversion process.
35. Both Places and References have woeids. The only issue is that references may have more than
one :-(
36.
37.
38.
39.
40. YQL open table for
GET and JSON
Another thing YQL allows developers to do is to extend it with own open tables that run JavaScript
conversions on the server side. One of those is the YQL open table which does all the things
Placemaker does on the server and offers JSON output.
41. Good news,
everyone!
The really nice thing of the open YQL table is that it already puts the places and references
together.
