Integrating Relational Databases with the Semantic Web

By: J.F. Sequeda

An early vision in Computer Science was to create intelligent systems capable of reasoning on larg¬e amounts of data. Independent results in the areas of Semantic Web and Relational Databases have advanced us towards this vision. Despite independent advances, the interface between Relational Databases and Semantic Web is poorly understood. This dissertation revisits this early vision with respect to current technology and addresses the following question: How and to what extent can Relational Databases be integrated with the Semantic Web? The thesis is that much of the existing Relational Database infrastructure can be reused to support the Semantic Web. Two problems are studied. Can a Relational Database be automatically virtualized as a Semantic Web data source? The first contribution is an automatic direct mapping from a Relational Database schema and data to RDF and OWL. The second contribution is a method capable of evaluating SPARQL queries against the Relational Database by exploiting two existing relational query optimizations. These contributions are embodied in the Ultrawrap system. Experiments show that SPARQL query execution performance on Ultrawrap is comparable to that of SQL queries written directly for the relational data. Such results have not been previously achieved. Can a Relational Database be mapped to existing Semantic Web ontologies and act as a reasoner? A third contribution is a method for Relational Databases to support inheritance and transitivity by compiling the ontology as mappings, implementing the mappings as views, using SQL recursion and optimizing by materializing views. Ultrawrap is extended with this contribution. Empirical analysis reveals that Relational Databases are able to effectively act as reasoners.

Rifts

Rift Worlds — Book 1

By: J F Mehentee

To save a world, he must risk his own. While testing fireworks, orphan Sam shoots down a dragon and her knight. A dying emperor begs his wife, Maria, to abdicate and avoid the ensuing power struggle for their failing empire. With her mind bound to the human who shot her out of the sky, Eliana upsets her father’s plans for returning their people to their home world. Rifts, invisible gates between worlds and a source of magical energy, connect the fates of Sam, Maria and Eliana. Sam’s destiny is to seal the Rifts. Unbeknown to Maria, her dead son and heir to the empire, Sam, still lives. And if the Rifts close, Eliana and her people can’t return home. Set in a world where animals host human souls, machines weave magic and people aren’t who they claim to be, Rifts is the first book in a three-part epic fantasy series.

The Dragon Pearl Series (Books 1-8)

Full Series

By: J F Mehentee

One mistake. Five lives. A universe in chaos. Inspired by Asian and Middle Eastern mythologies, The Dragon Pearl Series box set contains six novellas whose interconnected stories determine the fate of a universe in the novels Tamuda Rising and The Four-Day War. Packed with adventure, this complete 1400-page series is perfect for readers of epic fantasy. Book 1 - Hotsuka’s Story Banished from Heaven and no longer a Celestial, Hotsuka must adapt to his new life as the monk, Gaurang. Can he rescue his newborn son who’s destined to change the universe? Not everyone, however, wants change. Book 2 - Barid’s Story Barid, a once-elite warrior turned blacksmith, despised and ridiculed by villagers, waits for Noor: a man whom he’d die for; a man who may already be dead. When Gaurang arrives and promises the villagers a miracle, Barid must decide whether to remain a blacksmith or put his past and Noor behind him. Book 3 - Omid’s Story If he’s to save the Empire, Omid, the emperor’s sickly son, must complete Gaurang’s undertaking: to forge a sword so light and sharp it will cut a falling leaf. With a Dragoness out to sabotage the undertaking, can Omid complete the task in time, or will he plunge the Empire and the Dragonfolk back into endless war? Book 4 - Madhuri’s Story Captured by the nomadic Tamuda, Madhuri receives two gifts from a snake spirit. Thanks to the first gift, she is betrothed to the charismatic Chuluun. As Madhuri settles into her new life, she discovers her presence endangers the entire Tamuda nation. When the spirit’s second gift reveals itself, Madhuri realises she must sacrifice everything, including Chuluun. Book 5 - Babak’s Story Half-human and half-monkey, Babak befriends Kunie, the emperor’s daughter. Infatuated, he wants to be a guardsman and, one day, Kunie’s personal bodyguard. But Babak was born to serve a greater purpose. How will he react when he learns his commitment to Kunie and his destiny are not one and the same thing? Book 6 - Shernaz’s Story Abandoned by her husband, Shernaz is rescued by the Queen of Patalama and given a Dragon pearl. Thanks to the pearl, Shernaz enjoys prolonged youth and the independence she always dreamed of. When the pearl loses its power, obtaining a second carries a dreadful price. Book 7 – Tamuda Rising The Tamuda nation gathers and prepares for war. The Takeo Sura, a cabal of disgruntled Dragons, use deceit, cunning and murder to create chaos before the invading horde reaches the Imperial Fortress. While a desperate group of guardsmen try to hinder the Tamuda’s advance, the Fortress prepares for a siege. The Takeo Sura, however, have other ideas. In Tamuda Rising, the storylines for Gaurang, Barid, Omid, Kunie, Babak and Shernaz converge. Each has a role in determining the fate of the Empire and ultimately the universe. Book 8 – The Four-day War As the Tamuda battle their way into the Imperial Fortress, the Takeo Sura hamper the Empire’s attempts to defend itself. With Gaurang missing and news Babak has sided with the Tamuda, Kunie’s first days as empress are fraught. Meanwhile, Lady Shinju and the Meijin Council arrive on the Dragon Isles. Like Lord Takeo, she’s prepared for a four-day war, the outcome of which will decide the fate of humans, Dragons and gods alike. The Four-Day War is the eighth and final instalment in the Dragon Pearl Series.

Lincoln's Assassin

The Unsolicited Confessions of J Wilkes Booth

By: J F Pennington

In 1890, actor John Wilkes Booth long presumed dead emerged from twenty-five years of anonymity in his wilderness refuge to expose those truly responsible for the Lincoln assassination and its ensuing cover-up, to unite with the children he had never known and recover what he might of his sense of purpose and dignity. After shooting President Abraham Lincoln, Booth fled into the night, and government reports claimed he was killed twelve days later. But the man who was shot in the head and burned in a tobacco-shed fire before being covertly transported to Washington was never fully identified. Friends, as well as members of America's premier family of the theater of which he was a member, were barred from even viewing the body, the only photograph taken of the corpse was never printed, and then lost, and a strangely ceremonious martial court presided over a secret burial. Rumor immediately began to circulate: Booth was still alive.In Lincoln's Assassin, Jeffrey Pennington presents Booth's own story of flight and return, detailing how another was shot in his place as he escaped to nominal freedom and obscurity, leaving behind all his personal belongings and the stage-life he once knew. The larger conspiracy in which he was embroiled is unpicked in stylish fashion, exploring the political landscape in which Lincoln lived and died. Written in a confessional style, it aims to offer an insight into the true motivations at the heart of the Lincoln assassination, an event that continues to be the subject of much theorizing and interest.
